abort - terminate the process abnormally
#include <stdlib.h>
void abort(void);
Safe
abort() causes abnormal process
termination to occur, unless the signal SIGABRT
is being caught and the
signal handler does not return. The abnormal termination processing includes
at least the effect of fclose(3S)
on all open streams and message catalogue
descriptors, and the default actions defined for SIGABRT
. The SIGABRT
signal
is sent to the calling process as if by means of the raise(3C)
function
with the argument SIGABRT
.
The status made available to wait(2)
or waitpid(2)
by abort will be that of a process terminated by the SIGABRT
signal.
abort will override blocking or ignoring the SIGABRT
signal.

Catching the signal is intended to provide the application writer
with a portable means to abort processing, free from possible interference
from any implementation-provided library functions. If SIGABRT
is neither
caught nor ignored, and the current directory is writable, a core dump
may be produced.
