<color blue>**bool OS_Dtimer_Check (dtimer)**</color>\\ 
=== ===


Check dynamic timer //dtimer// for timeout.

##[[en:osa:ref:appendix:configuration#Timer control|OS_ENABLE_DTIMERS]]## constant must be defined in ##[[en:osa:ref:appendix:configuration|OSAcfg.h]]##. Size of dynamic timers is set by ##[[en:osa:ref:appendix:configuration#Data types|OS_DTIMER_SIZE]]## constant

=== Call allowed: ===
Everywhere


=== Parameters: ===
{| class = "fpl"
|-
|//''dtimer''//
|Descriptor of dynamic timer. Variable of ##[[en:osa:ref:description:data_types#OST_DTIMER|OST_DTIMER]]## type. Contains timer counter, timer state flags and pointer to next timer in list. For PIC16, can only be allocated in **bank0** or **bank1**
|}


=== Returns: ===
{| class = "fpl"
|-
|//''false''//
| no timeout
|-
|//''true''//
| timeout expired, timer has overflowed
|}


=== Example: ===
<code cpp>
OST_DTIMER dtimer;

void Task (void)
{
    for (;;) {
        /*...*/
        if (OS_Dtimer_Check (dtimer)) {        // If timer has overflowed
            OS_Dtimer_Update(dtimer, 1000);    // then re-run it
        };
        /*...*/
    }
}
