abort—abnormal termination of a program #include <stdlib.h>
void abort(void);
Description
Use abort to signal that your program has detected a condition it
cannot deal with. Normally, abort ends your program's execution.
Before terminating your program, abort raises the exception SIGABRT
(using `raise(SIGABRT)'). If you have used signal to register
an exception handler for this condition, that handler has the
opportunity to retain control, thereby avoiding program termination.
In this implementation, abort does not perform any stream- or
file-related cleanup (the host environment may do so; if not, you can
arrange for your program to do its own cleanup with a SIGABRT
exception handler).
Returns
abort does not return to its caller.
Portability
ANSI C requires abort.
Supporting OS subroutines required: _exit and optionally, write.
