Server-Supplied Manager EPVs

A server can (and sometimes must) create and register a non-null manager EPV for an interface. To select a server-application-supplied EPV, pass a non-null EPV whose value has been declared by the server as the value of the MgrEpv argument. A non-null value for the MgrEpv argument always overrides a default EPV in the server stub.

The MIDL compiler automatically generates a manager EPV data type (RPC_MGR_EPV) for a server application to use in constructing manager EPVs. A manager EPV must contain exactly one entry point (function address) for each procedure defined in the IDL file.

A server must supply a non-null EPV in the following cases:

• When the names of manager routines differ from the procedure names declared in the interface definition.
• When the server uses the default EPV for registering another implementation of the interface.

A server declares a manager EPV by initializing a variable of type if-name_SERVER_EPV for each implementation of the interface.
