ADM_CheckTimer

Syntax

int ADM_CheckTimer(ADMHANDLE adm_handle, unsigned short *adm_tmlast, long

*adm_tmout)

Parameters

adm_handle

Handle returned by previous call to ADM_Open.

adm_tmlast

Starting time of timer returned from call to ADM_StartTimer.

adm_tmout

Timeout value in microseconds.

Description

ADM_CheckTimer checks a timer for a timeout condition. Each time the function

is called, ADM_CheckTimer updates the current timer value in adm_tmlast and

the time remaining until timeout in adm_tmout. If adm_tmout is less than 0, then

a 1 is returned to indicate a timeout condition. If the timer has not expired, a 0 will

be returned.

adm_handle must be a valid handle returned from ADM_Open.

Return Value

Timer not expired.

Timer expired.

Example

Check 2 timers.

ADMHANDLE adm_handle;

unsigned short timer1;

unsigned short timer2;

long timeout1;

long timeout2;

timeout1 = 10000000L; /* set timeout for 10 seconds */

timer1 = ADM_StartTimer(adm_handle);

/* wait until timer 1 times out */

while(!ADM_CheckTimer(adm_handle, &timer1, &timeout1))

timeout2 = 5000000L; /* set timeout for 5 seconds */

timer2 = ADM_StartTimer(adm_handle);

/* wait until timer 2 times out */

while(!ADM_CheckTimer(adm_handle, &timer2, &timeout2))
