NAME
     PXFSIGPROCMASK - Examines and changes blocked signals

SYNOPSIS
     SUBROUTINE PXFSIGPROCMASK (ihow, jsigset, josigset, ierror)
     INTEGER ihow, jsigset, josigset, ierror

STANDARDS
     IEEE standard interface for FORTRAN 77

DESCRIPTION:
     The PXFSIGPROCMASK subroutine uses sigprocmask(2) to store the set of
     signals blocked from delivery and pending for the calling process.

     The following is a list of arguments for this routine:

     ihow      A default integer input variable containing the manner in
               which the set is changed.  The possible values are:

               SIG_BLOCK      Add to current mask set

               SIG_UNBLOCK    Delete from current mask set

               SIG_SETMASK    Replace current mask set

               This argument is ignored if josigset is NULL.  If ihow is
               zero, the current set is not changed.

               The value may also be set to SIG_NOP, which does not alter
               the current mask set. This value is equivalent to providing
               a NULL handle for josigset.

     jsigset   A default integer input variable containing a handle created
               by PXFSTRUCTCREATE(sigset,...).  If nonzero, the handle
               points to a set of signals that can be used to change the
               currently blocked set.

     josigset  A default integer output variable containing a handle
               created by PXFSTRUCTCREATE(sigset,...).  If nonzero, the
               handle will be set to the currently blocked signal set.  If
               zero, the currently blocked signal set will not be changed
               and the value of ihow is ignored.

     ierrno    A default integer output variable that contains zero if
               PXFSIGPPROCMASK was successful and nonzero if
               PXFSIGPPROCMASK was not successful.

     This subroutine may return any of the following error values:

     EFAULT         The jsigset or josigset argument points outside the
                    allocated space.

     EINVAL         The value of ihow is an invalid or unsupported
                    operation.

     EBADHANDLE     The jsigset argument is invalid.

     This routine is in libfortran.so which is linked by default when
     compiling programs with the MIPSpro 7 Fortran 90 compiler or when
     compiling programs with the -craylibs option to the MIPSpro F77
     compiler.

     All arguments must be of default kind unless documented otherwise. On
     IRIX systems, the default kind is KIND=4.

NOTES
     The PXF_DEFINITIONS module can be used by Fortran 90 users to enable
     caller-callee interface checking.

     Replace any Fortran reference to sigpprocmask() with a subroutine call
     to PXFSIGPROCMASK.
