Routine Description:

    Implementation of DDI entry point DrvEscape.
    Please refer to DDK documentation for more details.

Arguments:

    pso - Describes the surface the call is directed to
    iEsc - Specifies a query
    cjIn - Specifies the size in bytes of the buffer pointed to by pvIn
    pvIn - Points to input data buffer
    cjOut - Specifies the size in bytes of the buffer pointed to by pvOut
    pvOut -  Points to the output buffer

Return Value:

    Depends on the query specified by iEsc parameter
