+.SH NAME
+abort \- cause abnormal process termination
+.SH LIBRARY
+Standard C library
+.RI ( libc ", " \-lc )
+.SH SYNOPSIS
+.nf
+.B #include <stdlib.h>
+.P
+.B [[noreturn]] void abort(void);
+.fi
+.SH DESCRIPTION
+The
+.BR abort ()
+function first unblocks the
+.B SIGABRT
+signal, and then raises that signal for the calling process
+(as though
+.BR raise (3)
+was called).
+This results in the abnormal termination of the process unless the
+.B SIGABRT
+signal is caught and the signal handler does not return
+(see
+.BR longjmp (3)).
+.P
+If the
+.B SIGABRT
+signal is ignored, or caught by a handler that returns, the
+.BR abort ()
+function will still terminate the process.
+It does this by restoring the default disposition for
+.B SIGABRT
+and then raising the signal for a second time.
+.P
+As with other cases of abnormal termination the functions registered with
+.BR atexit (3)
+and
+.BR on_exit (3)
+are not called.
+.SH RETURN VALUE
+The
+.BR abort ()
+function never returns.
+.SH ATTRIBUTES
+For an explanation of the terms used in this section, see
+.BR attributes (7).

+.SH HISTORY
+SVr4, POSIX.1-2001, 4.3BSD, C89.
+.P
+Up until glibc 2.26,
+if the
+.BR abort ()
+function caused process termination,
+all open streams were closed and flushed (as with
+.BR fclose (3)).
+However, in some cases this could result in deadlocks and data corruption.
+Therefore, starting with glibc 2.27,
+.\" glibc commit 91e7cf982d0104f0e71770f5ae8e3faf352dea9f
+.BR abort ()
+terminates the process without flushing streams.
+POSIX.1 permits either possible behavior, saying that
+.BR abort ()
+"may include an attempt to effect fclose() on all open streams".
