VMS Help System Services, $IEEE SET FP CONTROL (Alpha Only)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    On Alpha systems, modifies the software IEEE floating-point
    control register and, optionally, returns the previous register
    value.

    The service provides the mechanism to set the specified bits in
    the IEEE floating-point control register, to clear the specified
    bits in the register, and to swap the values of the register.

    Format

      SYS$IEEE_SET_FP_CONTROL  [clrmsk] ,[setmsk] ,[prvmsk]

    C Prototype

      int sys$ieee_set_fp_control  (struct _ieee *clrmsk, struct

                                   _ieee *setmsk, struct _ieee

                                   *prvmsk);
