Description
Using is_DeviceInfo(), you can query information about connected USB 3 Cameras. The
resulting information is written to the IS_DEVICE_INFO structure. For this purpose, the cameras need
not be opened.
The nCommand input parameter is used to select the function mode. The pParam input parameter
depends on the selected function mode. If you select functions for setting or returning a value,
pParam contains a pointer to a variable of the UINT type. The size of the memory area to which
pParam refers is specified in the cbSizeOfParam input parameter.
