Applies only to SOME Unicode versions. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcecoreos5/html/wce50lrfCreateProcess.asp << BOOL CreateProcess( << LPCWSTR pszImageName, << LPCWSTR pszCmdLine, << [...] << pszCmdLine << [in, out] Pointer to a null-terminated string that specifies the << command line to execute. I have a vague recollection of some other place too where the API requires a pointer to constant so that the API can modify the user's constant.
From: anton on 27 Mar 2006 22:12 Hi guys Judging from what you are saying here, it looks like you just have discovered one more bug in Windows. Apparently, if COM library is initialized, execution takes a bit different path, so that memory leak does not occur. This seems to be the only logical explanation Regards Anton Bassov
