abort — cause abnormal process termination
#include <stdlib.h>
noreturn void
abort( |
void); |
The abort() function first
unblocks the SIGABRT signal,
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
SIGABRT signal is caught and
the signal handler does not return (see longjmp(3)).
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.
For an explanation of the terms used in this section, see attributes(7).

Thread safety | MT-Safe |
Up until glibc 2.26, if the abort() function caused process
termination, all open streams were closed and flushed (as
with fclose(3)). However, in
some cases this could result in deadlocks and data
corruption. Therefore, starting with glibc 2.27, abort() terminates the process without
flushing streams. POSIX.1 permits either possible behavior,
saying that abort() "may
include an attempt to effect fclose() on all open
streams".
