The following function can be used to check the error state on Enumeration knobs. If we have the EXACT_MATCH_ONLY flag set, any attempt to set an enumeration knob by name to an invalid value will result in the knob being in an Error state. This function can be used to get the error value (i.e. the value that was attempted to set. Returns NULL if no error.
