http://bugs.winehq.com/show_bug.cgi?id=1875 Summary: CoCreateGuid under wine generates rather weak guid's Product: Wine Version: unspecified Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-binary AssignedTo: wine-bugs(a)winehq.com ReportedBy: luolin(a)dreamwork.cn OS: redhat linux 9.0 wine: 20031118 rpm for rh9 (i386 & i686) the following code is a bare stream test app compiled under microsoft 2000 sp4 visual studio .net 2003. it generates quite pleasing guid's under windows, but when run the compiled binary directly under wine in my linux box, the generated guid's are quite weak - guid.Data1 (32 bits) is a pseudo random number, and the rest parts guid.Data2, guid.Data3, guid.Data4 are all the same for all the guid's generated. ============================ #include <tchar.h> #include <objbase.h> #include <windows.h> #include <iomanip> #include <iostream> int _tmain(int argc, _TCHAR* argv[]) { for (int i = 0; i < 1000; ++i) { GUID guid; CoCreateGuid(&guid); std::cout << std::hex << std::setw(8) << std::setfill('0') << guid.Data1 << ':'; std::cout << std::hex << std::setw(4) << std::setfill('0') << guid.Data2 << ':'; std::cout << std::hex << std::setw(4) << std::setfill('0') << guid.Data3 << ':'; UINT64 dnid; memcpy(&dnid, guid.Data4, 8); std::cout << std::hex << std::setw(16) << std::setfill('0') << dnid << std::endl; } return 0; } -- Configure bugmail: http://bugs.winehq.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
