Question
Timer function in C++
I am using alarm() to time a process.
Is there something with which i can measure by milliseconds ?
The alarm() in C++ allows only seconds and not anything lesser than that.
I did try ftime() and time(),But i need something to timeout automatically.
Thanks

Why you post in the C++Builder forum then? ;)
Just kidding, however, the PTimer class sounds like a good idea to me.
There's some documentation to it in: http://www.openh323.org/do
OR use POSIX timers, check http://www.nd.edu/~lemmon/
//Try this!!!
LONGLONG Frequency, CurrentTime, LastTime;
double TimeScale;
QueryPerformanceFrequency(
TimeScale = (1.0/Frequency)*1000.0;
QueryPerformanceCounter( (LARGE_INTEGER*) &LastTime);//begin measure
//Add the function in here
QueryPerformanceCounter( (LARGE_INTEGER*) &CurrentTime);//end measure
AnsiString milliseconds = (CurrentTime-LastTime)*Tim
//difference in milliseconds is (CurrentTime-LastTime)*Tim
