abort



ABORT(3)                   Library Functions Manual                   ABORT(3)


NAME

     abort - cause abnormal program termination


SYNOPSIS

     #include <stdlib.h>

     void
     abort(void);


DESCRIPTION

     The abort() function causes abnormal program termination to occur, unless
     the signal SIGABRT is being caught and the signal handler does not
     return.

     Some implementations may flush output streams before terminating.  This
     implementation does not.


RETURN VALUES

     The abort() function never returns.


SEE ALSO

     sigaction(2), exit(3)


STANDARDS

     The abort() function conforms to IEEE Std 1003.1-1990 (``POSIX.1'').


HISTORY

     The abort() function first appeared in Version 5 AT&T UNIX.

     Historically, previous standards required abort() to flush and close
     output streams, but this conflicted with the requirement that abort() be
     async signal safe.  As a result, the flushing requirement was dropped.
