I'm using OllyDbg 1.1 and am writing a plugin. I'd like to get all references (calls in particular) of a specified function. I can do this in the Olly GUI, but there is no documentation for the corresponding API function:

extc int cdecl Findreferences(ulong base,ulong size,ulong addr0,ulong addr1, ulong origin,int recurseonjump,char *title);

Could anyone please shed some light on what the correct values are if I want to retrieve alls calls to a function entry point?
