The following modifications rotate all the shapes created in the earlier example counter. Setitimer() - Set value of an interval timer For example, an a ITIMER_VIRTUAL timer will mark execution time for just the thread, not the entire process. 6.6 Example 6: Animation via Timer Function (GL06TimerFunc.cpp). Linux-programming-by-example - C code from the book "Linux Programming by Example" (void) setitimer(ITIMER_REAL, NULL, NULL) / turn off timer */. There is an example showing the use of the alarm function in Handler Returns. The alarm and setitimer functions provide a mechanism for a process to. Setitimer.c - simple use of the interval timer / #include / for setitimer / #include / for pause / #include / for signal / #define After the another example with setitimer() to implement a repetitive timer. You can use setitimer function on Unix to set a timer interval. setitimer() with ITIMER_REAL, send always SIGALRM. Hello, I would like to use several timers with setitimer, but I have a problem. The key here is that calling setitimer() results in the OS Here's an example from here which uses setitimer() to periodically call DoStuff(). The setitimer system call is a generalization of the alarm call. 8.13 setitimer: Setting Interval Timers. Please find my program snippet attached with this thread. I tried with unix funciton call setitimer. The setitimer() function sets the timer specified by which to the value in the example returns the current interval timer value using the setitimer() function: Microsoft made computers totally useless for my application when it changed from MS-DOS to Windows.Read Online > Read Online Setitimer example The intervals I need are based on real-world constants, and cannot be changed to accommodate Windows. The process is done wrong, and the desired result is not achieved. So, no matter what interval I really need, I get a longer interval which is at least 55 ms long. The random number term represents the time left in the 55 ms jiffy when the real-world event actually occurs, and the other term represents the actual time elapsed from the start of the timer to the output of the command to the real-world equipment. The total elapsed time is 55 ms times a random number in the range [0.1), plus 55 ms times the next highest integer of the quotient of the desired interval divided by 55 ms. Then, after the interval ends, Windows won't let the command be sent to the real-world equipment until the program's jiffy ends and Windows does the I/O during the mousekeeping period. When the real-world event which is supposed to start the interval occurs, Windows won't let the computer program know about it until the program's jiffy is over and Windows does the I/O during the mousekeeping period. The problem is that Windows takes a time-out every 55 milliseconds to do its mousekeeping, and all I/O must occur during the mouskeeping period. These are necessary for real-time control of equipment. I need to create time intervals in the millisecond range (e.g. If lngLoopCntr > lngMilliSecs then exit Do LngLoopCntr=0 ' although it initializes to 0, but it is a gud practise to initialize variable Private Declare Sub Sleep lib "kernel32" (ByVal dwMilliseconds as long) Depending on timer may effect the application, it reacts differently in different operating environments, i hope the code given below may help you
