Functions Implemented by Network Providers

The following functions are implemented by a network provider DLL to communicate with the Multiple Provider Router (MPR). Note that only the Capabilities Functions must be implemented by a network provider. Implementation of the other types of functions is optional and depends on the requirements of the network provider.
