rpc_cs_eval_without_universal- evaluates a server's supported character sets and code sets during the server binding selection process
void rpc_cs_eval_without_universal( rpc_ns_handle_t binding_handle, idl_void_p_t eval_args, idl_void_p_t *context);
- The server binding handle.
- An opaque data type that contains matching criteria that the routine uses to perform code sets compatibility evaluation.
- An opaque data type that contains search context to perform character and code sets compatibility evaluation. The routine returns the result of the evaluation in a field within context.
- Returns the status code from this routine. This status code indicates whether the routine completed successfully or, if not, why not.
Possible status codes and their meanings include:
The rpc_cs_eval_without_universal() routine evaluates, within an import context, the code sets and character sets supported by a server, providing a mechanism with which a client that is passing international character data can evaluate character and code sets compatibility before establishing a connection. It is one of the routines used for character and code set interoperability, which permits clients and servers to transfer international character data in a heterogeneous character set and code sets environment.
Client applications do not call rpc_cs_eval_without_universal() directly. Instead, they add it to the import context created by the rpc_ns_binding_import_begin() routine by calling the rpc_ns_import_ctx_add_eval() routine and specifying the routine name and the server entry name to be evaluated. When the application calls the rpc_ns_binding_import_next() routine to import binding handles for compatible servers, this routine calls the rpc_cs_eval_without_universal() routine, which then uses the rpc_cs_char_set_compat_check() routine to check character set compatibility between client and server.
The rpc_cs_eval_without_universal() routine directs the rpc_ns_binding_import_next() routine to reject servers with incompatible character sets. The routine also directs the rpc_ns_binding_import_next() routine to reject servers whose supported code sets are incompatible with the client's supported code sets, even if character set compatibility has been established. (By contrast, the rpc_cs_eval_with_universal() routine establishes tags that direct the client and/or server stubs to convert character data to the user-defined intermediate code set, if any, or the default, which is the ISO10646 (or universal) code set.)
