RpcBindingToStringBinding function (rpcdce.h)

The RpcBindingToStringBinding function returns a string representation of a binding handle.


RPC_STATUS RpcBindingToStringBinding(
  RPC_CSTR           *StringBinding



Client or server binding handle to convert to a string representation of a binding handle.


Returns a pointer to a pointer to the string representation of the binding handle specified in the Binding parameter.

Specify a null value to prevent RpcBindingToStringBinding from returning the StringBinding parameter. In this case, the application does not call the RpcStringFree function.

Return value

Value Meaning
The call succeeded.
The binding handle was invalid.
Note  For a list of valid error codes, see RPC Return Values.


The RpcBindingToStringBinding function converts a client or server binding handle to its string representation.

The RPC run-time library allocates memory for the string returned in the StringBinding parameter. The application is responsible for calling the RpcStringFree function to deallocate that memory.

If the binding handle in the Binding parameter contained a nil object UUID, the object UUID field is not included in the returned string.

To parse the returned StringBinding parameter, call the RpcStringBindingParse function.

Note  To query a client's address, an application starts by calling the RpcBindingServerFromClient function to obtain a partially bound server binding handle. The server binding handle can be used to obtain a string binding by invoking RpcBindingToStringBinding. The server can then call RpcStringBindingParse to extract the client's network address from the string binding.
