BOOL QueryPerformanceFrequency(
| LARGE_INTEGER *lpFrequency | // address of current frequency |
| ); |
Parameters
lpFrequency
Points to a variable that the function sets, in counts per second, to the current performance-counter frequency. If the installed hardware does not support a high-resolution performance counter, this parameter can be to zero.
