- Description
Obtain the name and ID of a webcam device based on its index.
- Parameters
- Index [in]
The specified index for the webcam device, ranging from 0 to the device count - 1.

The string buffer allocated to receive the webcam device name. Ensure that the buffer has a capacity greater than 260 characters.
- DeviceID [out]
The string buffer allocated to receive the webcam device ID. Ensure that the buffer has a capacity greater than 260 characters.
- Return Value
If the name and ID of a webcam device are successfully obtained, the return value is TRUE. Otherwise, the return value is FALSE.
- Remarks
Use this function to obtain the name and ID of a webcam device based on its index. If the index is greater than or equal to 0 and less than the total device count, the Device and DeviceID parameters will be assigned the corresponding webcam device's name and ID, and the function will return TRUE. Otherwise, both Device and DeviceID will be set to empty strings and the function will return FALSE. To obtain the count of webcam devices currently connected to the system, call ScnLib_GetWebcamDeviceCount().
