Used by client applications.

Synopsis

void rpc_ns_binding_import_begin(

unsigned32 entry_name_syntax,

Parameters

Input

entry_name_syntax
An integer value that specifies the syntax of parameter entry_name.

To use the syntax specified in the RPC_DEFAULT_ENTRY_SYNTAX environment variable, provide the value rpc_c_ns_syntax_default.

entry_name
Specifies the entry name where the search for compatible binding handles begins. This can be either the global or cell-relative name.

To use the entry name found in the RPC_DEFAULT_ENTRY environment variable, supply NULL or a null string (\0) for this parameter. When this entry name is used, the RPC runtime automatically uses the default name syntax specified in the RPC_DEFAULT_ENTRY_SYNTAX environment variable.

if_handle
A stub-generated data structure specifying the interface to import. If the interface specification has not been exported or is of no concern to the caller, specify NULL for this parameter. In this case the bindings returned are only guaranteed to be of a compatible and supported protocol sequence and, depending on the value of parameter obj_uuid, contain the specified object UUID. The desired interface may not be supported by the contacted server.

obj_uuid
Specifies an optional object UUID.

If you specify NULL or a nil UUID for this parameter, the returned binding handles contain one of the object UUIDs that the compatible server exported. If the server did not export any object UUIDs, the returned compatible binding handles contain a nil object UUID.

If you specify a non-nil UUID, compatible binding handles are returned from an entry only if the server has exported the specified object UUID. Each returned binding handle contains the specified non-nil object UUID.

Output

import_context
Returns the name service handle for use with the rpc_ns_binding_import_next( ) and rpc_ns_binding_import_done( ) routines.

status
Returns the status code from this routine. This status code indicates whether the routine completed successfully or, if not, why not.

The possible status codes and their meanings are as follows:

rpc_s_ok	Success.
rpc_s_incomplete_name	Incomplete name.
rpc_s_invalid_name_syntax	Invalid name syntax.
rpc_s_invalid_object	Invalid object.
rpc_s_no_env_setup	Environment variable not set up.
rpc_s_unsupported_name_syntax	Unsupported name syntax.

Description
The rpc_ns_binding_import_begin( ) routine creates an import context for importing compatible server binding handles for servers. These servers offer the specified interface and object UUID in the respective if_handle and obj_uuid parameters.

Before calling rpc_ns_binding_import_next( ), the client must first call this routine to create an import context. The arguments to this routine control the operation of rpc_ns_binding_import_next( ).

After importing binding handles, the client calls rpc_ns_binding_import_done( ) to delete the import context.

Permissions Required
No permissions are required.

Return Values
No value is returned.
