abort(3C) Standard C Library Functions abort(3C)
abort - terminate the process abnormally
#include <stdlib.h>
void abort(void);
The abort() function 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(3C) on all open streams and message catalogue descrip‐
tors, 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 over‐
ride blocking or ignoring the SIGABRT signal.
The abort() function does not return.
No errors are defined.
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.
