Using OpenCV I believe you could just do:

CvCapture* cap = cvCaptureFromCAM(0);
if(!cap)
{
   printf("no camera or can't connect to camera...\n");
}

The OP posted as an answer:
"and if cam is busy? for busy cam it's not work"
"I'm sorry but I can't find it in documentation OpencV. Only this variant if(!cap)"
(I have deleted the spurious answer)
