- // Function:
- //
- // FindLibrary()
- //
- // Purpose:
- //
- // Called to get the fragment/file name of a Mac Shared Library given
- // the library's creator and codec ID. The Codec ID is stored in STR#9000;
- // item #1 of the library.
- //
- // Parameters:
- //
- // HX_MOFTAG moftCodecTag
- // The four character codec identifier (RV10, dnet, ...)
- //
- // OSType codecCreator
- // The Creator type of the codec; currently kDecoderCreator or kEncoderCreator
- //
- // char* pLibName
- // Allocate this before calling FindLibrary. Library file name is
- // returned in it. Library's fragment name should be same as file name!!
- //
- // Return:
- //
- // HX_RESULT
- // Error code indicating the success or failure of the function.
- //
- #if defined(_CARBON) || defined(_MAC_UNIX)
