include module type of struct include Printexc end

type t = exn = ..

The type of exception values.

val to_string_default : exn -> string

Printexc.to_string_default e returns a string representation of the exception e, ignoring all registered exception printers.

since 4.09

val use_printers : exn -> string option

Printexc.use_printers e returns None if there are no registered printers and Some s with else as the resulting string otherwise.

Raw backtraces

Current call stack

Uncaught exceptions

val default_uncaught_exception_handler : exn -> Printexc.raw_backtrace -> unit

Printexc.default_uncaught_exception_handler prints the exception and backtrace on standard error output.

Manipulation of backtrace information

These functions are used to traverse the slots of a raw backtrace and extract information from them in a programmer-friendly format.
