ABORT(3) Linux Programmer's Manual ABORT(3)
abort - cause abnormal process termination
#include <stdlib.h>
void abort(void);
The abort() 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 abort() function causes process termination, all open streams
are closed and flushed.
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.
The abort() function never returns.
For an explanation of the terms used in this section, see
attributes(7).
