The RpcBindingFree function releases binding-handle resources.

Syntax

RPC_STATUS RpcBindingFree(
  RPC_BINDING_HANDLE *Binding
);

Parameters

Binding

Pointer to the server binding to be freed.

Return value

Value	Meaning
RPC_S_OK	The call succeeded.
RPC_S_INVALID_BINDING	The binding handle was invalid.
RPC_S_WRONG_KIND_OF_BINDING	This was the wrong kind of binding for the operation.

Note For a list of valid error codes, see RPC Return Values.

Remarks

The RpcBindingFree function releases memory used by a server binding handle. Referenced binding information that was dynamically created during program execution is released as well. An application calls the RpcBindingFree function when it is finished using the binding handle. RPC binding handles must not be freed until all calls using the handle have completed; failure to do so will cause unpredictable results.

Binding handles are dynamically created by calling the following functions:

If the operation successfully frees the binding, the Binding parameter returns a value of NULL.

Note Microsoft RPC supports RpcBindingFree only in client applications, or in server applications for binding handles generated with RpcBindingServerFromClient.
