pxfsigprocmask(3F)

NAME
     PXFSIGPROCMASK - Examines and changes blocked signals

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

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

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.

               On IRIX systems, 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.

     On IRIX systems, 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.

     When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
     UNICOS, UNICOS/mk, or IRIX systems, all arguments must be of default
     kind unless documented otherwise. On UNICOS and UNICOS/mk, default
     kind is KIND=8 for integer, real, complex, and logical arguments; on
     IRIX systems, the default kind is KIND=4.

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