NAMEsiglongjmp --- non-local goto with signal handling
#include <setjmp.h> void siglongjmp(sigjmp_buf env, int val);
DESCRIPTIONThe 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.
RETURN VALUEAfter 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.
ERRORSNo errors are defined.
The following sections are informative.
APPLICATION USAGEThe distinction between setjmp() or longjmp() and sigsetjmp() or siglongjmp() is only significant for programs which use sigaction(), sigprocmask(), or sigsuspend().
