sigret(2)                        DG/UX 5.4.2                       sigret(2)


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

SYNOPSIS
       #include <signal.h>

       void  sigret ()

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.

DIAGNOSTICS
       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.
