.SH NAME
siglongjmp \- non-local goto with signal handling
.SH SYNOPSIS
.LP
\fB#include <setjmp.h>
.br
.sp
void siglongjmp(sigjmp_buf\fP \fIenv\fP\fB, int\fP \fIval\fP\fB);

.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.
.SH ERRORS
.LP
No errors are defined.
.LP
\fIThe following sections are informative.\fP
.SH EXAMPLES
.LP
None.
.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
.LP
None.
.SH FUTURE DIRECTIONS
.LP
None.
