Macro to get Thread/Zone Name

Abhijeet

I'm trying to get the face name using the Macro THREAD_NAME(t). The UDF compiles but when I execute it, the Macro does not return me the face name. THREAD_ID(t) and THREAD_TYPE(t) work as they should.

part of code with the above macro usage

char *name; thread_loop_f(t,d) { name = THREAD_NAME(t);}

Suggestions please. Thank you Abhijeet
