C code help

[Sirrius]

All I'm trying to do here is calculate the clock time of the computer with a couple C functions. The author of the book tells me "kind of" how to do it but still kind of vague. I am getting a number, but it doesn't seem to be close to the clock speed of the computer(which is 133mhz, yeah yeah, I know it's slow but it boots my embedded apps okay)instead I'm getting a number like 231851640624.......about 20 digits long. Can somebody tell me what I'm doing wrong with my code? Thanks. #include "libepc.h" int main(void) { ClearScreen(0x07) ; SetCursorPosition(10,20); DWORD32 timeout; long long speed; speed=CPU_Clock_Cycles(); PutUnsigned(speed,10,0); timeout = Now_Plus(1); while(Now_Plus(0) < timeout) { speed=CPU_Clock_Cycles(); } PutUnsigned(speed,10,0); return 0 ; }
