+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult

+or the interface may not be implemented on Linux.

+.SH NAME
+siglongjmp
+\(em non-local goto with signal handling
+.SH SYNOPSIS
+.LP
+.nf
+#include <setjmp.h>
+.P
+void siglongjmp(sigjmp_buf \fIenv\fP, int \fIval\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIsiglongjmp\fR()
+function shall be equivalent to the
+\fIlongjmp\fR()
+function, except as follows:
+.IP " *" 4
+References to
+\fIsetjmp\fR()
+shall be equivalent to
+\fIsigsetjmp\fR().
+.IP " *" 4
+The
+\fIsiglongjmp\fR()
+function shall restore the saved signal mask if and only if the
+.IR env
+argument was initialized by a call to
+\fIsigsetjmp\fR()
+with a non-zero
+.IR savemask
+argument.
+.SH "RETURN VALUE"
+After
+\fIsiglongjmp\fR()
+is completed, program execution shall continue as if the corresponding
+invocation of
+\fIsigsetjmp\fR()
+had just returned the value specified by
+.IR val .
+The
+\fIsiglongjmp\fR()
+function shall not cause
+\fIsigsetjmp\fR()
+to return 0; if
+.IR val
+is 0,
+\fIsigsetjmp\fR()
+shall return the value 1.
+.SH ERRORS
+No errors are defined.
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+None.
+.SH "APPLICATION USAGE"
+The distinction between
+\fIsetjmp\fR()
+or
+\fIlongjmp\fR()
+and
+\fIsigsetjmp\fR()
+or
+\fIsiglongjmp\fR()
+is only significant for programs which use
+\fIsigaction\fR(),
+\fIsigprocmask\fR(),
+or
+\fIsigsuspend\fR().
+.SH RATIONALE
+None.
+.SH "FUTURE DIRECTIONS"
+None.
