SIGLONGJMP(3P) POSIX Programmer's Manual SIGLONGJMP(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
siglongjmp — non-local goto with signal handling
#include <setjmp.h>
void siglongjmp(sigjmp_buf env, int val);
The siglongjmp() function shall be equivalent to the longjmp()
function, except as follows:
* References to setjmp() shall be equivalent to sigsetjmp().
* The siglongjmp() function shall restore the saved signal mask if
and only if the env argument was initialized by a call to
sigsetjmp() with a non-zero savemask argument.
After siglongjmp() is completed, program execution shall continue as
if the corresponding invocation of sigsetjmp() had just returned the
value specified by val. The siglongjmp() function shall not cause
sigsetjmp() to return 0; if val is 0, sigsetjmp() shall return the
value 1.
No errors are defined.
The following sections are informative.
None.
The distinction between setjmp() or longjmp() and sigsetjmp() or
siglongjmp() is only significant for programs which use sigaction(),
sigprocmask(), or sigsuspend().
None.
