_exit

Syntax

#include <unistd.h> void _exit(int exit_code);

Description

This function exits the program, returning exit_code to the calling process. No additional processing (such as closing file descriptors or calls to the static destructor functions) is done, and any atexit functions are not called; only the hardware interrupt handlers are unhooked, to prevent system crashes e.g. after a call to abort. This function is normally called only by exit and abort.

Return Value

This function does not return.
