int eth32cfg_plugin_choose_interface(eth32cfgiflist handle, int index);
This function selects one of the available network interfaces on the PC as the interface on which the ETH32 Configuration / Detection API should sniff for responses from ETH32 devices. This does not affect the main API functionality. The interface list must have been previously obtained using the eth32cfg_plugin_interface_list function and the provided index must be a valid index within that list. Currently, this function is only applicable when the WinPcap plugin is loaded. Otherwise, the ETH_NOT_SUPPORTED error will be returned.
handle - The value returned by eth32cfg_plugin_interface_list
index - The index of the interface in the previously-obtained interface list which should be chosen for sniffing responses
This function returns zero on success and a negative error code on failure. Please see the Error Codes section for possible error codes.
