Exceptions
val raise : exn -> 'a

Raise the given exception value

val raise_notrace : exn -> 'a

A faster version raise which does not record the backtrace.

  • since 4.02.0
val invalid_arg : string -> 'a

Raise exception Invalid_argument with the given string.

val failwith : string -> 'a

Raise exception Failure with the given string.

exception Exit

The Exit exception is not raised by any library function. It is provided for use in your programs.

Comparisons
val (==) : 'a -> 'a -> bool

e1 == e2 tests for physical equality of e1 and e2. On mutable types such as references, arrays, byte sequences, records with mutable fields and objects with mutable instance variables, e1 == e2 is true if and only if physical modification of e1 also affects e2. On non-mutable types, the behavior of ( == ) is implementation-dependent; however, it is guaranteed that e1 == e2 implies compare e1 e2 = 0.

  • deprecated [since 2014-10] Use [phys_equal]
val (!=) : 'a -> 'a -> bool

Negation of (==).

  • deprecated [since 2014-10] Use [phys_equal]
Boolean operations
val not : bool -> bool

The boolean negation.

val (&&) : bool -> bool -> bool

The boolean 'and'. Evaluation is sequential, left-to-right: in e1 && e2, e1 is evaluated first, and if it returns false, e2 is not evaluated at all.

val (&) : bool -> bool -> bool
  • deprecated [since 2010-01] {!Caml.( && )} should be used instead.
val (||) : bool -> bool -> bool

The boolean 'or'. Evaluation is sequential, left-to-right: in e1 || e2, e1 is evaluated first, and if it returns true, e2 is not evaluated at all.

val or : bool -> bool -> bool
  • deprecated [since 2010-01] {!Caml.( || )} should be used instead.
Debugging

Integer arithmetic

Integers are 31 bits wide (or 63 bits on 64-bit processors). All operations are taken modulo 231 (or 263). They do not fail on overflow.

val (~-) : int -> int

val (~+) : int -> int

Unary addition. You can also write + e instead of ~+ e.

  • since 3.12.0
val succ : int -> int

val (+) : int -> int -> int

Integer addition.

val (-) : int -> int -> int

Integer subtraction.

val (*) : int -> int -> int

Integer multiplication.

val (/) : int -> int -> int

Integer division. Raise Division_by_zero if the second argument is 0. Integer division rounds the real quotient of its arguments towards zero. More precisely, if x >= 0 and y > 0, x / y is the greatest integer less than or equal to the real quotient of x by y. Moreover, (- x) / y = x / (- y) = - (x / y).

val (mod) : int -> int -> int

Integer remainder. If y is not zero, the result of x mod y satisfies the following properties: x = (x / y) * y + x mod y and abs(x mod y) <= abs(y) - 1. If y = 0, x mod y raises Division_by_zero. Note that x mod y is negative only if x < 0. Raise Division_by_zero if y is zero.

val abs : int -> int

Return the absolute value of the argument. Note that this may be negative if the argument is min_int.

val (lsr) : int -> int -> int

n lsr m shifts n to the right by m bits. This is a logical shift: zeroes are inserted regardless of the sign of n. The result is unspecified if m < 0 or m >= bitsize.

val (asr) : int -> int -> int

n asr m shifts n to the right by m bits. This is an arithmetic shift: the sign bit of n is replicated. The result is unspecified if m < 0 or m >= bitsize.

Floating-point arithmetic

OCaml's floating-point numbers follow the IEEE 754 standard, using double precision (64 bits) numbers. Floating-point operations never raise an exception on overflow, underflow, division by zero, etc. Instead, special IEEE numbers are returned as appropriate, such as infinity for 1.0 /. 0.0, neg_infinity for -1.0 /. 0.0, and nan ('not a number') for 0.0 /. 0.0. These special numbers then propagate through floating-point computations as expected: for instance, 1.0 /. infinity is 0.0, and any arithmetic operation with nan as argument returns nan as result.

val (~-.) : float -> float

Unary negation. You can also write -. e instead of ~-. e.

val (~+.) : float -> float

Opening modes for Caml.open_out_gen and Caml.open_in_gen.

  • deprecated [since 2016-04] Use [In_channel.create] and [Out_channel.create]
val open_out : string -> Caml.out_channel

Open the named file for writing, and return a new output channel on that file, positionned at the beginning of the file. The file is truncated to zero length if it already exists. It is created if it does not already exists.

  • deprecated [since 2016-04] Use [Out_channel.create]
val open_out_bin : string -> Caml.out_channel

Same as Caml.open_out, but the file is opened in binary mode, so that no translation takes place during writes. On operating systems that do not distinguish between text mode and binary mode, this function behaves like Caml.open_out.

  • deprecated [since 2016-04] Use [Out_channel.create]
val open_out_gen : Caml.open_flag list -> int -> string -> Caml.out_channel

open_out_gen mode perm filename opens the named file for writing, as described above. The extra argument mode specify the opening mode. The extra argument perm specifies the file permissions, in case the file must be created. Caml.open_out and Caml.open_out_bin are special cases of this function.

  • deprecated [since 2016-04] Use [Out_channel.create]
val flush : Caml.out_channel -> unit

Flush the buffer associated with the given output channel, performing all pending writes on that channel. Interactive programs must be careful about flushing standard output and standard error at the right time.

  • deprecated [since 2016-04] Use [Out_channel.flush]
val flush_all : unit -> unit

Flush all open output channels; ignore errors.

  • deprecated [since 2016-04]

val output : Caml.out_channel -> bytes -> int -> int -> unit

output oc buf pos len writes len characters from byte sequence buf, starting at offset pos, to the given output channel oc. Raise Invalid_argument "output" if pos and len do not designate a valid range of buf.

  • deprecated [since 2016-04] Core doesn't yet support bytes.
val output_substring : Caml.out_channel -> string -> int -> int -> unit

Same as output but take a string as argument instead of a byte sequence.

  • deprecated [since 2016-04] Use [Out_channel.output]
val output_byte : Caml.out_channel -> int -> unit

Write one 8-bit integer (as the single character with that code) on the given output channel. The given integer is taken modulo 256.

  • deprecated [since 2016-04] Use [Out_channel.output_byte]
val output_binary_int : Caml.out_channel -> int -> unit

Write one integer in binary format (4 bytes, big-endian) on the given output channel. The given integer is taken modulo 232. The only reliable way to read it back is through the Caml.input_binary_int function. The format is compatible across all machines for a given version of OCaml.

  • deprecated [since 2016-04] Use [Out_channel.output_binary_int]
val output_value : Caml.out_channel -> 'a -> unit

Write the representation of a structured value of any type to a channel. Circularities and sharing inside the value are detected and preserved. The object can be read back, by the function Caml.input_value. See the description of module Marshal for more information. Caml.output_value is equivalent to Marshal.to_channel with an empty list of flags.

  • deprecated [since 2016-04] Use [Out_channel.output_value]
val seek_out : Caml.out_channel -> int -> unit

seek_out chan pos sets the current writing position to pos for channel chan. This works only for regular files. On files of other kinds (such as terminals, pipes and sockets), the behavior is unspecified.

  • deprecated [since 2014-10] Use [Out_channel.seek]
val pos_out : Caml.out_channel -> int

Return the current writing position for the given channel. Does not work on channels opened with the Open_append flag (returns unspecified results).

  • deprecated [since 2014-10] Use [Out_channel.pos]
val out_channel_length : Caml.out_channel -> int

Return the size (number of characters) of the regular file on which the given channel is opened. If the channel is opened on a file that is not a regular file, the result is meaningless.

  • deprecated [since 2014-10] Use [Out_channel.length]
val close_out : Caml.out_channel -> unit

Close the given channel, flushing all buffered write operations. Output functions raise a Sys_error exception when they are applied to a closed output channel, except close_out and flush, which do nothing when applied to an already closed channel. Note that close_out may raise Sys_error if the operating system signals an error when flushing or closing.

  • deprecated [since 2014-10] Use [Out_channel.close]
val close_out_noerr : Caml.out_channel -> unit

Same as close_out, but ignore all errors.

  • deprecated [since 2016-04] Use [Out_channel.close] and catch exceptions
val set_binary_mode_out : Caml.out_channel -> bool -> unit

set_binary_mode_out oc true sets the channel oc to binary mode: no translations take place during output. set_binary_mode_out oc false sets the channel oc to text mode: depending on the operating system, some translations may take place during output. For instance, under Windows, end-of-lines will be translated from \n to \r\n. This function has no effect under operating systems that do not distinguish between text mode and binary mode.

General input functions
val open_in : string -> Caml.in_channel

Open the named file for reading, and return a new input channel on that file, positionned at the beginning of the file.

  • deprecated [since 2016-04] Use [In_channel.create]
val open_in_bin : string -> Caml.in_channel

Same as Caml.open_in, but the file is opened in binary mode, so that no translation takes place during reads. On operating systems that do not distinguish between text mode and binary mode, this function behaves like Caml.open_in.

  • deprecated [since 2016-04] Use [In_channel.create]
val open_in_gen : Caml.open_flag list -> int -> string -> Caml.in_channel

open_in_gen mode perm filename opens the named file for reading, as described above. The extra arguments mode and perm specify the opening mode and file permissions. Caml.open_in and Caml.open_in_bin are special cases of this function.

  • deprecated [since 2016-04] Use [In_channel.create]
val input_char : Caml.in_channel -> char

Read one character from the given input channel. Raise End_of_file if there are no more characters to read.

  • deprecated [since 2016-04] Use [In_channel.input_char]
val input_line : Caml.in_channel -> string

Read characters from the given input channel, until a newline character is encountered. Return the string of all characters read, without the newline character at the end. Raise End_of_file if the end of the file is reached at the beginning of line.

  • deprecated [since 2016-04] Use [In_channel.input_line]
val input : Caml.in_channel -> bytes -> int -> int -> int

input ic buf pos len reads up to len characters from the given channel ic, storing them in byte sequence buf, starting at character number pos. It returns the actual number of characters read, between 0 and len (inclusive). A return value of 0 means that the end of file was reached. A return value between 0 and len exclusive means that not all requested len characters were read, either because no more characters were available at that time, or because the implementation found it convenient to do a partial read; input must be called again to read the remaining characters, if desired. (See also Caml.really_input for reading exactly len characters.) Exception Invalid_argument "input" is raised if pos and len do not designate a valid range of buf.

  • deprecated [since 2016-04] Core doesn't yet support bytes.
val really_input : Caml.in_channel -> bytes -> int -> int -> unit

really_input ic buf pos len reads len characters from channel ic, storing them in byte sequence buf, starting at character number pos. Raise End_of_file if the end of file is reached before len characters have been read. Raise Invalid_argument "really_input" if pos and len do not designate a valid range of buf.

  • deprecated [since 2016-04] Core doesn't yet support bytes.
val really_input_string : Caml.in_channel -> int -> string

really_input_string ic len reads len characters from channel ic and returns them in a new string. Raise End_of_file if the end of file is reached before len characters have been read.

  • deprecated [since 2016-04] Use [In_channel.really_input_exn ~pos:0]
val input_byte : Caml.in_channel -> int

Same as Caml.input_char, but return the 8-bit integer representing the character. Raise End_of_file if an end of file was reached.

  • deprecated [since 2016-04] Use [In_channel.input_byte]
val input_binary_int : Caml.in_channel -> int

Read an integer encoded in binary format (4 bytes, big-endian) from the given input channel. See Caml.output_binary_int. Raise End_of_file if an end of file was reached while reading the integer.

  • deprecated [since 2016-04] Use [In_channel.input_binary_int]
val input_value : Caml.in_channel -> 'a

Read the representation of a structured value, as produced by Caml.output_value, and return the corresponding value. This function is identical to Marshal.from_channel; see the description of module Marshal for more information, in particular concerning the lack of type safety.

  • deprecated [since 2016-04] Use [In_channel.unsafe_input_value]
val seek_in : Caml.in_channel -> int -> unit

seek_in chan pos sets the current reading position to pos for channel chan. This works only for regular files. On files of other kinds, the behavior is unspecified.

  • deprecated [since 2014-10] Use [In_channel.seek]
val pos_in : Caml.in_channel -> int

Return the current reading position for the given channel.

  • deprecated [since 2014-10] Use [In_channel.pos]
val in_channel_length : Caml.in_channel -> int

Return the size (number of characters) of the regular file on which the given channel is opened. If the channel is opened on a file that is not a regular file, the result is meaningless. The returned size does not take into account the end-of-line translations that can be performed when reading from a channel opened in text mode.

  • deprecated [since 2014-10] Use [In_channel.length]
val close_in : Caml.in_channel -> unit

Close the given channel. Input functions raise a Sys_error exception when they are applied to a closed input channel, except close_in, which does nothing when applied to an already closed channel.

  • deprecated [since 2014-10] Use [In_channel.close]
val close_in_noerr : Caml.in_channel -> unit

Same as close_in, but ignore all errors.

  • deprecated [since 2016-04] Use [In_channel.close] and catch exceptions
val set_binary_mode_in : Caml.in_channel -> bool -> unit

set_binary_mode_in ic true sets the channel ic to binary mode: no translations take place during input. set_binary_mode_out ic false sets the channel ic to text mode: depending on the operating system, some translations may take place during input. For instance, under Windows, end-of-lines will be translated from \r\n to \n. This function has no effect under operating systems that do not distinguish between text mode and binary mode.

  • deprecated [since 2016-04] Use [In_channel.set_binary_mode]
Operations on large files
module LargeFile = Core_kernel.LargeFile

Operations on large files. This sub-module provides 64-bit variants of the channel functions that manipulate file positions and file sizes. By representing positions and sizes by 64-bit integers (type int64) instead of regular integers (type int), these alternate functions allow operating on files whose sizes are greater than max_int.

References
type 'a ref = 'a Caml.ref = {
  1. mutable contents : 'a;
}

The type of references (mutable indirection cells) containing a value of type 'a.

val ref : 'a -> 'a ref

Return a fresh reference containing the given value.

val (!) : 'a ref -> 'a

!r returns the current contents of reference r. Equivalent to fun r -> r.contents.

val (:=) : 'a ref -> 'a -> unit

r := a stores the value of a in reference r. Equivalent to fun r v -> r.contents <- v.

val incr : int ref -> unit

Increment the integer contained in the given reference. Equivalent to fun r -> r := succ !r.

val decr : int ref -> unit

Decrement the integer contained in the given reference. Equivalent to fun r -> r := pred !r.

Result type

type ('a, 'b) result = ('a, 'b) Caml.result =
  1. | Ok of 'a
  2. | Error of 'b
Operations on format strings

Format strings are character strings with special lexical conventions that defines the functionality of formatted input/output functions. Format strings are used to read data with formatted input functions from module Scanf and to print data with formatted output functions from modules Printf and Format.

Format strings are made of three kinds of entities:

  • conversions specifications, introduced by the special character '%' followed by one or more characters specifying what kind of argument to read or print,
  • formatting indications, introduced by the special character '@' followed by one or more characters specifying how to read or print the argument,
  • plain characters that are regular characters with usual lexical conventions. Plain characters specify string literals to be read in the input or printed in the output.

There is an additional lexical rule to escape the special characters '%' and '@' in format strings: if a special character follows a '%' character, it is treated as a plain character. In other words, "%%" is considered as a plain '%' and "%@" as a plain '@'.

For more information about conversion specifications and formatting indications available, read the documentation of modules Scanf, Printf and Format.

type ('a, 'b, 'c, 'd, 'e, 'f) format6 = ('a, 'b, 'c, 'd, 'e, 'f) CamlinternalFormatBasics.format6

Format strings have a general and highly polymorphic type ('a, 'b, 'c, 'd, 'e, 'f) format6. The two simplified types, format and format4 below are included for backward compatibility with earlier releases of OCaml.

The meaning of format string type parameters is as follows:

  • 'a is the type of the parameters of the format for formatted output functions (printf-style functions); 'a is the type of the values read by the format for formatted input functions (scanf-style functions).
  • 'b is the type of input source for formatted input functions and the type of output target for formatted output functions. For printf-style functions from module Printf, 'b is typically out_channel; for printf-style functions from module Format, 'b is typically Format.formatter; for scanf-style functions from module Scanf, 'b is typically Scanf.Scanning.in_channel.

Type argument 'b is also the type of the first argument given to user's defined printing functions for %a and %t conversions, and user's defined reading functions for %r conversion.

  • 'c is the type of the result of the %a and %t printing functions, and also the type of the argument transmitted to the first argument of kprintf-style functions or to the kscanf-style functions.
  • 'd is the type of parameters for the scanf-style functions.
  • 'e is the type of the receiver function for the scanf-style functions.
  • 'f is the final result type of a formatted input/output function invocation: for the printf-style functions, it is typically unit; for the scanf-style functions, it is typically the result type of the receiver function.
type ('a, 'b, 'c, 'd) format4 = ('a, 'b, 'c, 'c, 'c, 'd) format6
type ('a, 'b, 'c) format = ('a, 'b, 'c, 'c) format4
val string_of_format : ('a, 'b, 'c, 'd, 'e, 'f) format6 -> string

Converts a format string into a string.

val format_of_string : ('a, 'b, 'c, 'd, 'e, 'f) format6 -> ('a, 'b, 'c, 'd, 'e, 'f) format6

format_of_string s returns a format string read from the string literal s. Note: format_of_string can not convert a string argument that is not a literal. If you need this functionality, use the more general Scanf.format_from_string function.

val (^^) : ('a, 'b, 'c, 'd, 'e, 'f) format6 -> ('f, 'b, 'c, 'e, 'g, 'h) format6 -> ('a, 'b, 'c, 'd, 'g, 'h) format6

f1 ^^ f2 catenates format strings f1 and f2. The result is a format string that behaves as the concatenation of format strings f1 and f2: in case of formatted output, it accepts arguments from f1, then arguments from f2; in case of formatted input, it returns results from f1, then results from f2.

Program termination
val exit : int -> 'a

Terminate the process, returning the given status code to the operating system: usually 0 to indicate no errors, and a small positive integer to indicate failure. All open output channels are flushed with flush_all. An implicit exit 0 is performed each time a program terminates normally. An implicit exit 2 is performed if the program terminates early because of an uncaught exception.

val at_exit : (unit -> unit) -> unit

Register the given function to be called at program termination time. The functions registered with at_exit will be called when the program executes Caml.exit, or terminates, either normally or because of an uncaught exception. The functions are called in 'last in, first out' order: the function most recently added with at_exit is called first.
