abort - terminate the process abnormally
The abort() function causes abnormal process termination to
occur, unless the signal SIGABRT is being caught and the
signal handler does not return. 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(2) or waitpid(2) by
abort will be that of a process terminated by the SIGABRT
signal. abort will override blocking or ignoring the
The abort() function does not return.
No errors are defined.
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 neither caught nor
ignored, and the current directory is writable, a core dump
may be produced.
