Captive Network Support is a system component responsible for detecting and help users navigate networks that require interaction before providing internet access. The most common Captive Networks are WiFi Hotspots in places like airports, restaurants, and hotels. Captive Network Support will attempt to authenticate if possible or drop a user in to a web sheet if authentication is not possible. In the web sheet the user has an opportunity to authenticate or disassociate from the network. The following APIs are designed for third party applications that may handle authentication on these networks on behalf of the user. These APIs are treated as advisory only. There is no guarantee or contract that the operating system will take the intended action. */ __BEGIN_DECLS /*! @function CNSetSupportedSSIDs @discussion Provides Captive Network Support with an updated list of SSIDs that this application will perform authentication on.
