  NAME

    fpe_did_unload - Unloads an Floating point Engine (FPE) coprocessor image

  LIBRARY

    Intergraph Device Library (libix.a)

  SYNOPSIS

    #include <sys/xio/xerr.h>

    int fpe_did_unload(
      int fpeno,did );

  PARAMETERS

    fpeno   A Floating-Point Engine number

    did     An identification number

  DESCRIPTION

    The fpe_did_unload() function unloads a Floating-Point Engine (FPE)
    microcode image which was loaded using fpe_did_load().  The fpeno
    parameter, returned by fpe_coproc_alloc(), is the number of the FPE to be
    unloaded by the driver.

    The did parameter is the identification number of the microcode image to
    be unloaded obtained by fpe_did_load().

  RETURN VALUES

    Upon successful completion, a value of 0 is returned.  Otherwise, one of
    the above failure codes is returned.

  ERRORS

    The fpe_did_unload() function will fail if one of the following is true:

    [XIO_FAILURE]
           The system does not contain the driver needed to support this
           request.

    [FPE_NOT_PRESENT]
           The value of fpeno specifies an invalid FPE.

    [FPE_NOT_OWNER]
           The value of fpeno specifies an FPE that is not currently allocated
           by the process.

    [FPE_DID_OUT_OF_RANGE]
           The value of did specifies a microcode image greater than the
           maximum number supported by the driver.

    [FPE_DID_NONEXISTENT]
           The value of did specifies a microcode image that is not currently
           loaded in the FPE.
