.Fn abort void
.Sh DESCRIPTION
The

function causes abnormal program termination to occur, unless the signal
.Dv SIGABRT
is being caught and the signal handler does not return.
.Pp
Some implementations may flush output streams before terminating.
This implementation does not.
.Sh RETURN VALUES

function never returns.
.Sh SEE ALSO

.Xr exit 3

.Fn abort
function conforms to
.St -p1003.1-90 .
.Sh HISTORY
The
.Fn abort
function first appeared in
.At v5 .

to flush and close output streams, but this conflicted with the requirement
that
.Fn abort

As a result, the flushing requirement was dropped.
