Timer for Multiple Platforms

Theres a bunch of standard library functions provided in that you should be able to use.

I need to know the time in seconds. Either seconds passes sincs computer has started or time in seconds ... for instance ... if 1 minute and 30 seconds have passed ... it should return 90 seconds. Which function should I use?

Between ... does it support the three OS i.e. Win, Linux and MAC OS?

Did you even try to google this? There is a C function called time located in time.h that returns a time in seconds... ... ...

#include <time.h>float getSeconds(){	return (float)clock()/(float)CLOCKS_PER_SEC;}

Yes! I searched for that and find a couple of remakes ... but I am not sure wether they will work on other platforms besides Windows ... I have to make sure that my code works on Linux and MAC OS the same way without any changes for some one ... and I don't have Linux nor MAC OS. So, I have to only choose those functions that are perfectly sured to be working in the three Operating Systems.

IIRC, this should work..

#include <ctime>time_t getTime() {  return time(NULL);}

The functions found in time.h / ctime (they're the same thing, except ctime is for use with C++, and has it's functions located within the std namespace) are standard. They should be available on all development environments. If they arn't, it's horribly broken*, since well, it's standard :-).

*(ctime won't exist on older compilers however)

Remember that clock() (if it exists at all), returns the CPU time used, not the elapsed time. So it's effectively useless for determining wall-clock time.

yes, the time() function works on all platforms and returns the time in seconds. For less than that, use the more accurate functions which are platform specific (hint: win32 = QueryPerformanceCounter or something, Unix-like=gettimeofday )

Thanks ... I don't need the function for counting FPS ... its for something else ... anyway ... clock() works perfectly as per my requirement.

Thank you guys (Y)
