You can use GetLogicalProcessorInformation to get the info you need.
ETA:
As mentioned in the question a commenter linked to, another (easier) way to do it would be via GetSystemInfo:
Seems like GetLogicalProcessorInformation would give you more detailed info, but if all you need is the number of processors, GetSystemInfo would probably work just fine.
