1.timeSetEvent方法的第一个参数，最长时间间隔不能超过1000s，即1000000毫秒，超过返回失败。

MMRESULT timeSetEvent(   UINT           uDelay,   UINT           uResolution,   LPTIMECALLBACK lpTimeProc,   DWORD_PTR      dwUser,   UINT           fuEvent);

typedef struct timecaps_tag {  UINT wPeriodMin;  UINT wPeriodMax;} TIMECAPS, *PTIMECAPS, *NPTIMECAPS, *LPTIMECAPS;

Members

wPeriodMin: The minimum supported resolution, in milliseconds.
wPeriodMax: The maximum supported resolution, in milliseconds.

timeGetDevCaps需要Winmm.lib，在properties->linker->input->Additional Dependencies出添加。

TIMECAPS tc;
if(timeGetDevCaps(&tc, sizeof(TIMECAPS))==TIMERR_NOERROR ){
UINT min = tc.wPeriodMin;
UINT max = tc.wPeriodMax;
printf("min: %u, max: %u", min, max);
}
