NAMEabort - cause abnormal process termination
#include <stdlib.h>void abort(void);
DESCRIPTIONThe abort() first unblocks the SIGABRTsignal, and then raises that signal for the calling process (as though raise(3) was called). This results in the abnormal termination of the process unless the SIGABRTsignal is caught and the signal handler does not return (see longjmp(3)).
If the abort() function causes process termination, all open streams are closed and flushed.
If the SIGABRTsignal is ignored, or caught by a handler that returns, the abort() function will still terminate the process. It does this by restoring the default disposition for SIGABRTand then raising the signal for a second time.
RETURN VALUEThe abort() function never returns.
