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.
The abort() function
is thread-safe.
