StormLib API Reference
bool WINAPI SFileOpenPatchArchive( HANDLE hMpq, // Handle to an open MPQ (primary MPQ) const char * szMpqName, // Patch archive file name const char * szPatchPathPrefix, // Prefix for patch file names DWORD dwFlags // Reserved );
Function SFileOpenPatchArchive adds a patch archive to the existing open MPQ. The MPQ must have been open by SFileOpenArchive, and also with MPQ_OPEN_READ_ONLY specified. The patch archive is added to the list of patches that belong to the primary MPQ. No handle is returned, and the patch(es) is closed when the primary MPQ handle is closed. The patch MPQ opened during the process is maintained internally by StormLib and cannot be accessed directly.
When the function succeeds, it returns nonzero. When the archive cannot be added as patch archive, function returns false and GetLastError gives the error code.
The following table shows how patch prefix works:
