In apputils.c, it's clearly copied from https://stackoverflow.com/questions/5404277/porting-clock-gettime-to-windows but that implementation, and the one in coturn, are wrong. Posix defines clock_gettime() in terms of struct timespec { t...

KStrClockGetTime 是系統提供的例程,可擷取目前的系統時間。 KStrClockGetPhysicalTime 是系統提供的例程,可擷取目前的系統時間減去任何暫止的差異。 語法 C++ 複製 PFNKSCLOCK_GETTIME PfnksclockGettime; LONGLONG PfnksclockGettime( [in] PFILE_OBJECT FileObject ) {...} 參數 [in] FileObject 建立時...
When compiling on Windows 7 with VS2015 I was getting an error that clock_gettime was undefined in datetime.h To fix it I had to add the following code: #ifdef WIN32 #define NOMINMAX #define WIN32_LEAN_AND_MEAN #include <windows.h> #endi...
