_exit, _Exit - terminate the calling process
void _exit(int status);
#include <stdlib.h>
void _Exit(int status);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
_Exit(): _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE; or cc -std=c99
The value status is returned to the parent process as the process's exit status, and can be collected using one of the wait(2) family of calls.
The function _Exit() is equivalent to _exit().
The function _exit() is like exit(3), but does not call any functions registered with atexit(3) or on_exit(3). Whether it flushes standard I/O buffers and removes temporary files created with tmpfile(3) is implementation-dependent. On the other hand, _exit() does close open file descriptors, and this may cause an unknown delay, waiting for pending output to finish. If the delay is undesired, it may be useful to call functions like tcflush(3) before calling _exit(). Whether any pending I/O is canceled, and which pending I/O may be canceled upon _exit(), is implementation-dependent.
