RpcNsBindingInqEntryNameW function (rpcdce.h)
The RpcNsBindingInqEntryName function returns the entry name from which the binding handle came.
Syntax
RPC_STATUS RpcNsBindingInqEntryNameW(
RPC_BINDING_HANDLE Binding,
unsigned long EntryNameSyntax,
RPC_WSTR *EntryName
);
Parameters
Binding
Binding handle whose name-service database entry name is returned.
EntryNameSyntax
Syntax used in EntryName.
To use the syntax specified in the registry value entry
HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\NameService\DefaultSyntax, provide a value of RPC_C_NS_SYNTAX_DEFAULT.
EntryName
Returns the address of a pointer to the name of the name-service database entry in which Binding was found.
Specify a null value to prevent RpcNsBindingInqEntryName from returning the EntryName parameter. In this case, the application does not call the RpcStringFree function.
Return value
Value | Meaning |
---|---|
|
The call succeeded. |
|
The binding handle was invalid. |
|
No entry name for binding. |
|
The name syntax is invalid. |
|
The name syntax is unsupported. |
|
The name is incomplete. |
Remarks
The RpcNsBindingInqEntryName function returns the name of the name service–database entry name from which a client compatible–binding handle came.
The RPC run-time library allocates memory for the string returned in the EntryName parameter. The application is responsible for calling the RpcStringFree function to deallocate that memory.
An entry name is associated only with binding handles returned from the RpcNsBindingImportNext, RpcNsBindingLookupNext, and RpcNsBindingSelect functions.
If the binding handle specified in the Binding parameter was not returned from a name-service database entry (for example, if the binding handle was created by calling RpcBindingFromStringBinding), RpcNsBindingInqEntryName returns an empty string ("\0") and an RPC_S_NO_ENTRY_NAME status code.
Note
The rpcdce.h header defines RpcNsBindingInqEntryName as an alias which 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 not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
