timers in c++

[carmen]

Hello,

I have been searching msdn, but to no avail. Can anyone tell me if
there are any timer functions available for c++? (unmanaged). I want to
be able to set a timer, while accomplishing other tasks. If the timer
expires, the application exits.

Thanks,
Carmen

try alarm(), ftime(), and time()

 

[blueblueblue2005]

#include <unistd.h>
unsigned int alarm(unsigned int time_value);

this is actually a c function, but can be called in c++ program

Hi,

Thanks . I checked it out. But the problem is, I need to set the
timer and continue processing! When the timer expires, an event handler
should take over. Is this possible in c++?

Hi,

Thanks :again . But, I am developing on windows. This is a unix
header right?

Thanks,
Carmen

GetTickCount(); in milisec
QueryPerformanceCounter(); in microsec


__int64 cnt()
{
__int64 res;

__asm
{
rdtsc

mov dword ptr [res], eax
mov dword ptr [res + 4], edx
}

return res;
} // count of processor ticks.

If you are trying to create timers on windows, ther are two kinds:

WaitableTimers :
http://msdn.microsoft.com/library/d...en-us/dllproc/base/waitable_timer_objects.asp

Windows Timers:
http://msdn.microsoft.com/library/d...nui/windowsuserinterface/windowing/timers.asp
Both may be used for your application.
