);Parameters
- proc:
A calling-program-supplied callback function that allows your application to monitor progress or abort the operation.

Overview
The CMIterateCMMInfo function returns information for all CMMs installed on the system. The caller can pass nil for the CMMIterateUPP param to simply get a count of CMMs. If a CMMIterateUPP proc is provided, it is called once for each CMM installed - with the CMMInfo structure filled accordingly. The caller can pass a data reference to CMIterateCMMInfo which will then be passed to the CMMIterateUPP. This might be used to allow some of the information in the CMMInfo data structure to be put into a menu, for example, by passing a menu reference as the refcon. Either the proc or the count parameter must be provided. The caller will get a paramErr if both are nil.
