#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(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.
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.
