Remarks

The RpcBindingFromStringBinding function creates a server binding handle from a string representation of a binding handle. The StringBinding parameter does not have to contain an object UUID. In this case, the returned binding contains a nil UUID. If the provided StringBinding parameter does not contain an endpoint field, the returned Binding parameter is a partially-bound binding handle. If the provided StringBinding parameter contains an endpoint field, the endpoint is considered to be a well-known endpoint. If the provided StringBinding parameter does not contain a host address field, the returned Binding parameter references the local host.

An application creates a string binding by calling the RpcStringBindingCompose function or by providing a character-string constant. The creation of a string binding by this method does not involve contact with the server. Success or failure of the API will not indicate server availability.

When an application is finished using the Binding parameter, the application should call the RpcBindingFree function to release the memory used by the binding handle.

Note

The rpcdce.h header defines RpcBindingFromStringBinding as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
