Note
This command is supported by DCC3240x USB3 cameras only!
Syntax
INT is_DeviceInfo (HIDS hCam, UINT nCommand, void* pParam, UINT cbSizeOfParam)
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.
