val pread : fd:Unix.file_descr -> fd_offset:Optint.Int63.t -> buffer:bytes -> buffer_offset:int -> length:int -> int

Reads up to length bytes from fd (starting at position fd_offset) into buffer (starting at position buffer_offset). Returns the number of bytes actually read. fd's cursor position is unchanged.

val pwrite : fd:Unix.file_descr -> fd_offset:Optint.Int63.t -> buffer:bytes -> buffer_offset:int -> length:int -> int

Writes up to length bytes from buffer (starting at position buffer_offset) to the file descriptor fd (starting at position fd_offset). Returns the number of bytes actually written. fd's cursor position is unchanged.
