-.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 STANDARDS
-C11, POSIX.1-2008.
-.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".
