NAME
rpc_cs_eval_without_universal - Evaluates a server's supported
character sets and code sets
during the server binding
selection process
Used indirectly by client applications.
SYNOPSIS
#include <dce/rpc.h>
void rpc_cs_eval_without_universal( rpc_ns_handle_t binding_handle,
idl_void_p_t eval_args,
idl_void_p_t *context );
PARAMETERS
Input
binding_handle
The server binding handle.
eval_args
An opaque data type that contains matching criteria that the
routine uses to perform code sets compatibility evaluation.
Input/Output
context
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.
DESCRIPTION
The rpc_cs_eval_without_universal() routine is a DCE RPC character
and code sets evaluation routine that can be added to an import
context. The routine provides a mechanism for a client application
that is passing character data in a heterogeneous character set and
code sets environment to evaluate a server's character and code sets
compatibility before establishing a connection with it.
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 routine
rpc_ns_import_ctx_add_eval() and specifying the routine name and
the RPC server entry name to be evaluated. When the client
application calls the rpc_ns_binding_import_next() routine to import
compatible binding handles for servers, this routine calls
rpc_cs_eval_without_universal(), which applies client-server code
sets compatibility checking as another criteria for compatible
binding selection.
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; that is, it does not resort to using an intermediate
code set as a last resort.
Application programmers need not pay attention to the arguments of
this routine. They only need to use the rpc_ns_import_ctx_add_eval()
to set the routine, for example:
rpc_ns_import_ctx_add_eval( &import_context,
rpc_c_eval_type_codesets,
(void *) nsi_entry_name,
rpc_cs_eval_without_universal,
NULL,
&status );
Permissions Required
No permissions are required.
RETURN VALUES
No value is returned.
