abort(3C)                Standard C Library Functions                abort(3C)

NAME
       abort - terminate the process abnormally

SYNOPSIS
       #include <stdlib.h>

       void abort(void);

DESCRIPTION
       The  abort() function causes abnormal process termination to occur, un‐
       less the signal SIGABRT is caught and the signal handler does  not  re‐
       turn.  The abnormal termination processing includes at least the effect
       of fclose(3C) 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(3C) or waitpid(3C) by abort  will  be
       that of a process terminated by the SIGABRT signal. abort will override
       blocking or ignoring the SIGABRT signal.

RETURN VALUES
       The abort() function does not return.

ERRORS
       No errors are defined.

USAGE
       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 nei‐
       ther caught nor ignored, a core dump may be produced.
