ABORT(3) Library Functions Manual ABORT(3)
abort - generate a fault
abort() first closes all open files if possible, then sends an IOT sig-
nal to the process. This signal usually results in termination with a
core dump, which may be used for debugging.
It is possible for abort() to return control if SIGIOT is caught or
ignored, in which case the value returned is that of the kill(2V) sys-
adb(1), exit(2V), kill(2V), signal(3V)
If SIGIOT is neither caught nor ignored, and the current directory is
writable, a core dump is produced and the message `abort - core dumped'
is written by the shell.
