SIGLONGJMP(P) POSIX Programmer's Manual SIGLONGJMP(P)NAMEsiglongjmp - non-local goto with signal handling
SYNOPSIS
#include <setjmp.h>
void siglongjmp(sigjmp_buf env, int val);
DESCRIPTION
The siglongjmp() function shall be equivalent to the longjmp() func‐
tion, 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.
RETURN VALUE
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.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
The distinction between setjmp() or longjmp() and sigsetjmp() or sig‐
longjmp() is only significant for programs which use sigaction(), sig‐
procmask(), or sigsuspend().
RATIONALE
None.
FUTURE DIRECTIONS
None.
