     sigret(2)                  DG/UX 4.30                   sigret(2)



     NAME
          sigret - Restore the process state to that contained in a
          signal frame.

     SYNOPSIS
          #include <signal.h>

          void    sigret ()

     PARAMETERS
          None.

     DESCRIPTION
          The sigret call restores the process state to that contained
          in a signal frame pointed to by r31.  These values (with the
          exception of the four modifiable fields, SXIP, SNIP, SFIP,
          and r31) must be identical to the values in a signal frame
          that was pushed onto the user's stack when the process's
          signal handler was invoked (that is, this is a "return from
          signal handler").

     ACCESS CONTROL
          None.

     RETURN VALUE
          This function never returns.  Execution resumes at the point
          specified by the sigcontext structure.  If an error occurs,
          this function terminates the process with an exit status
          which indicates that the process was killed by a SIGSEGV
          signal.

     EXCEPTIONS
          Errno may be set to one of the following error codes:

          EFAULT         The sigcontext structure pointed to by r31
                         could not be accessed.

          EINVAL         The sigcontext structure pointed to by r31
                         contains invalid information.
