Enumeration Functions

If your network provider needs to support browsing of its network resources, it should implement the following functions. MPR calls these functions to enumerate the resources.

A network provider is not required to implement any of the enumeration functions. If, however, a network provider implements either NPOpenEnum, NPEnumResource, or NPCloseEnum, it must also implement the other two enumeration functions.

Function	Description
NPOpenEnum	Opens an enumeration of network resources or existing connections.
NPEnumResource	Performs an enumeration on a handle returned by NPOpenEnum.
NPCloseEnum	Closes an enumeration.
NPGetResourceInformation	Determines whether the provider is the correct provider to respond to a request for a specified network resource and returns information about the resource's type.
NPGetResourceParent	Returns the parent of a specified network resource in the browse hierarchy.
