Remarks
Windows CE supports only typelib2 type libraries.
The function LoadRegTypeLib defers to LoadTypeLib to load the file.
LoadRegTypeLib compares the requested version numbers against those found in the system registry, and takes one of the following actions:
- If a registered library exactly matches the requested major and minor version numbers, that type library is loaded.
- If one or more registered type libraries exactly match the requested major version number, and has a greater minor version number than that requested, the one with the greatest minor version number is loaded.
- If no registered type library exactly matches the requested major version number (or if none of those that exactly match the major version number have a minor version number greater than or equal to the requested minor version number), LoadRegTypeLib returns an error.
Passing invalid (and under some circumstances NULL) pointers to this function causes an unexpected termination of the application.
