abort3
Cause abnormal process termination
Usage
#include <stdlib.h>
[[noreturn]] void abort(void);
Library
Standard C library (libc, -lc)
Overview
The abort() function first unblocks the SIGABRT signal, and then raises that signal for the calling process (as though raise(3) was called). This results in the abnormal termination of the process unless the SIGABRT signal is caught and the signal handler does not return (see longjmp(3)).
If the SIGABRT signal is ignored, or caught by a handler that returns, the abort() function will still terminate the process. It does this by restoring the default disposition for SIGABRT and then raising the signal for a second time.
As with other cases of abnormal termination the functions registered with atexit(3) and on_exit(3) are not called.
Return value
The abort() function never returns.
