10.2. Determining the Number of AI Devices in a System

For the Audio Input (AI) board devices, there is a new class name, DEV_CLASS_AUDIO_IN, that is used with the sr_getboardcnt( ) function to return the number of AI devices in the system. So, if you issue sr_getboardcnt(DEV_CLASS_AUDIO_IN, &BrdCt), BrdCt is filled in with the number of AI board devices in the system.

For example:

int BrdCt = 0;  
sr_getboardcnt(DEV_CLASS_AUDIO_IN, &BrdCt);

The device name for AI devices is aiBn, where n is the board number starting at 1. Note that there are no channel devices on AI devices, only board devices.
