BUG: SetupGetFileCompressionInfo w/LocalFree Causes Access Error

MORE INFORMATION

The second parameter of SetupGetFileCompressionInfo() is the address of an LPSTR variable. If the function succeeds, SetupGetFileCompressionInfo() returns the full path of the file that was loaded. The documentation incorrectly states that you should free this string with a call to LocalFree(). Instead, the application should use MyFree().

Following is an example of how to obtain the MyFree() function from the SetupAPI.dll:

   typedef VOID (WINAPI* MYFREEFUNC)(LPVOID lpBuff);
   MYFREEFUNC MyFree;

   HMODULE hDll=NULL;
   hDll = GetModuleHandle("SETUPAPI.DLL");
   MyFree = (MYFREEFUNC)GetProcAddress(hDll, "MyFree");
   ...
   other code here to prepare file queue
   ...
   PTSTR lpActualSourceFileName;
   SetupGetFileCompressionInfo(...,&lpActualSourceFileName,...,...,...);
   ...
   MyFree(lpActualSourceFileName);
				

If the call to LocalFree is causing an Access Violation, you should solve the problem by using MyFree().
