sigsetjmp(3)               DG/UX 4.30                sigsetjmp(3)



     NAME
          sigsetjmp, siglongjmp - Non-local jumps.

     FUNCTIONS
          sigsetjmp(), siglongjmp()

     SYNOPSIS
          #include <setjmp.h>

          int sigsetjmp (env, savemask)
          sigjmp_buf env;
          int savemask;

          void siglongjmp (env, val)
          sigjmp_buf env;
          int val;

     DESCRIPTION
          The sigsetjmp macro shall comply with the definition of the
          setjmp macro in the C Standard.  If the value of the
          savemask argument is not zero, the sigsetjmp() function
          shall also save the process's current signal mask (see
          <signal.h>) as part of the calling environment.

          The siglongjmp() function shall comply with the definition
          of the longjmp() function in the C Standard.  If and only if
          the env argument was initialized by a call to the
          sigsetjmp() function with a non-zero savemask argument, the
          siglongjmp() function shall restore the saved signal mask.

     SEE ALSO

          setjmp(3C), longjmp(3C)
