Re: [ts-7000] Timer

["Charlie Wallace" <>]

something like this.

static void(*pUserTimerCB)(int x);

static void timer_func( int x )
{
    signal(SIGALRM, timer_func);

    if( pUserTimerCB ) {
        pUserTimerCB( x );
    }
}

/**
 * SetupTimerCallback -
 *
 * @param iUs - Number of microseconds to run the callback
 * @timeFunc - Pointer to a void function( int x ) to call every µs/microseconds
 *
 */
int SetupTimerCallback( unsigned long iUs , void (*timeFunc)(int x))
{
    struct itimerval timer;

    pUserTimerCB = timeFunc;

    signal(SIGALRM, timer_func);

   timer.it_value.tv_sec = timer.it_interval.tv_sec = 0;
   timer.it_value.tv_usec = timer.it_interval.tv_usec = (__suseconds_t)( iUs );

    return setitimer( ITIMER_REAL, &timer, NULL);
}
