I'm trying to code a program in vxworks. When a task total delay is 400 ticks, it was suspended at the 100th tick for 20 ticks, then resume to delay.
My main code is like the following:
void DelaySuspend (int level)
{
int tid, suspend_start,suspend_end,i;
suspend_start = vxTicks + 100;
suspend_end = vxTicks + 120;
i = vxTicks;
/* myfunction has taskDelay(400)*/
tid = taskSpawn("tMytask",200,0,2000,(FUNCPTR)myfunction,0,0,0,0,0,0,0,0,0,0);
/* tick between vxTicks+100 and vxTicks+120,suspend tMytask*/
while (i<suspend_start)
{
i=tickGet();
}
while (i <= suspend_end &&i >= suspend_start)
{
i = tickGet();
taskSuspend(tid);
}
}
What I want is to verify total delay time(or tick) doesn't change even I suspend the task for some time. I know the answer but just try to program it to show how vxWorks does it.
