I've found that calling pthread_self() results in the value returned by GetLastError() and WSAGetLastError() being reset. pthread_self() calls pthread_getspecific() which calls TlsGetValue(). The Win32 documentation for TlsGetValue() states: "Win32 functions that return indications of failure call SetLastError when they fail. They generally do not call SetLastError when they succeed. The TlsGetValue function is an exception to this general rule. The TlsGetValue function calls SetLastError to clear a thread's last error when it succeeds." ... I have fixed this by doing a GetLastError() and SetLastError() around the TlsGetValue() call to save and restore the last error. This fixes my specific problem, I'm just wondering whether you guys want to implement it in the pthreads-win32 library, or whether you consider it for the caller of the library to do around the pthread_self() call.
