DOC: GetProcAddress Does Not Support Ordinal Symbols

ID: Q149515

The information in this article applies to:

Microsoft Visual C++, Macintosh Cross-Development Addon, version 4.0

SUMMARY

GetProcAddress() returns NULL when passing a valid ordinal value for a DLL's exported function. The Macintosh Windows Portability Layer implementation of GetProcAddress() does not support obtaining exported function addresses by the function's ordinal value.

MORE INFORMATION

DLLs on the Macintosh are implemented using Code Fragment Libraries (CFM) on Power Macintoshes. Apple's implementation of CFMs only allows symbols to be exported by name. Therefore, you must use the exported function name to obtain the function address.
