I have several FirePro 2460 card. And I need to active all the displays. When I use ADL_Adapter_Active_Set to do this work, some of it failed and return -1.Can someone tell how this situaton happened. My code is as follow:
iRet = ADL_Adapter_NumberOfAdapters_Get(&iAdpaterCount);
if ((ADL_OK != iRet) || (iAdpaterCount < 2))
{
printf("Get adapter count failed!\n");
return 0;
}
pAdapterInfo = (LPAdapterInfo)malloc(iAdpaterCount * sizeof(AdapterInfo));
if (NULL == pAdapterInfo)
{
printf("Alloc adapter information failed!\n");
return 0;
}
iRet = ADL_Adapter_AdapterInfo_Get(pAdapterInfo, iAdpaterCount * sizeof(AdapterInfo));
if (ADL_OK != iRet)
{
printf("Get adapter information failed!\n");
return 0;
}
for (int i = 0; i < iAdpaterCount; i++)
{
iAdapterIndex = pAdapterInfo.iAdapterIndex;
iRet = ADL_Adapter_Active_Get(iAdapterIndex, &iStatus);
if ((ADL_OK != iRet) || (ADL_TRUE == iStatus))
{
continue;
}
iStatus = ADL_TRUE;
iRet = ADL_Adapter_Active_Set(iAdapterIndex, iStatus, &iNewlyActive);
}
