The
abort()
first unblocks the
SIGABRT
signal, and then raises that signal for the calling process.
This results in the abnormal termination of the process unless the
SIGABRT
signal 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
SIGABRT
signal 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
SIGABRT
and then raising the signal for a second time.
