C标准库里有没有计时函数？
类似于GetTickCount的，精度毫秒级以上。 找到了……clock
Libraries
All versions of the C run-time libraries.
Calculates the wall-clock time used by the calling process.
clock_t clock( void );
Return Value
The elapsed wall-clock time since the start of the process (elapsed time in seconds times CLOCKS_PER_SEC). If the amount of elapsed time is unavailable, the function returns –1, cast as a clock_t.
各位请WS掉吧。
