.SH NAME
|

|
siglongjmp \- non-local goto with signal handling
|
||
|
.SH SYNOPSIS
|
||
|
.LP
|
||

\fB#include <setjmp.h>
|

.SH DESCRIPTION
|
||
|
.LP
|
||
|
The \fIsiglongjmp\fP() function shall be equivalent to the \fIlongjmp\fP()
|
||
|
function,
|
||
|
except as follows:
|
||
|
.IP " *" 3
|
||
|
References to \fIsetjmp\fP() shall be equivalent to \fIsigsetjmp\fP().
|
||
|
.LP
|
||
|
.IP " *" 3
|
||
|
The \fIsiglongjmp\fP() function shall restore the saved signal mask
|
||
|
if and only if the \fIenv\fP argument was initialized by a
|
||
|
call to \fIsigsetjmp\fP() with a non-zero \fIsavemask\fP argument.
|
||
|
.LP
|
||
|
.SH RETURN VALUE
|
||
|
.LP
|
||
|
After \fIsiglongjmp\fP() is completed, program execution shall continue
|
||
|
as if the corresponding invocation of \fIsigsetjmp\fP() had just returned
|
||
|
the value specified by \fIval\fP. The \fIsiglongjmp\fP()
|
||
|
function shall not cause \fIsigsetjmp\fP() to return 0; if \fIval\fP
|
||
|
is 0, \fIsigsetjmp\fP() shall return the value 1.
|
||
|

No errors are defined.

.SH APPLICATION USAGE
|
||
|
.LP
|
||
|
The distinction between \fIsetjmp\fP() or \fIlongjmp\fP() and \fIsigsetjmp\fP()
|
||
|
or
|
||
|
\fIsiglongjmp\fP() is only significant for programs which use \fIsigaction\fP(),
|
||
|
\fIsigprocmask\fP(), or \fIsigsuspend\fP().
|
||
|
.SH RATIONALE
|
||
|
