Hi Peter,

Could you show me how you use these calls?

[Charles Pegge]

When you use full prototypes:

Code: [Select]

! QueryPerformanceCounter    Lib "kernel32.dll" (quad *c)  
! QueryPerformanceFrequency Lib "kernel32.dll" (quad *c)  
! Sleep Lib "kernel32.dll" (long ms)  
quad qf,qc1,qc2
double qt

 
QueryPerformanceFrequency qf   'this is how it works!
QueryPerformanceCounter   qc1

Sleep 100
QueryPerformanceCounter   qc2
qt=(qc2-qc1)/qf
print str qt,6
