NAME
    CxFilter -- create a commodity filter object. (V36)

SYNOPSIS
    filterObj = CxFilter(description);

    CxObj *CxFilter(STRPTR)

FUNCTION
    Creates an input event filter object that matches the
    'description' string. If 'description' is NULL, the filter will not
    match any messages.

    A filter may be modified by the functions SetFilter(), using
    a description string, and SetFilterIX(), which takes a
    binary Input Expression as a parameter.

    This function is a C-language macro for CreateCxObj(), defined
    in <libraries/commodities.h>.

INPUTS
    description - the description string in the same format as strings
                  expected by commodities.library/SetFilter()

RESULTS
    filterObj - a pointer to the filter object, or NULL if there
                was not enough memory. If there is a problem in the
                description string, the internal error code of the filter
                object will be set to so indicate. This error code may be
                interrogated using the function CxObjError().
