Returns one member name at a time from a group

Used by client, server, or management applications.

Synopsis

#include <dce/rpc.h>

void rpc_ns_group_mbr_inq_next(

rpc_ns_handle_t inquiry_context,

unsigned_char_t **member_name,

unsigned32 *status);

Parameters

Input

inquiry_context
Specifies a name service handle. This handle is returned from the rpc_ns_group_mbr_inq_begin( ) routine.

Output

member_name
Returns a pointer to a (global) RPC group member name. The syntax of the returned name is specified by the member_name_syntax parameter in rpc_ns_group_mbr_inq_begin( ).

Specify NULL to prevent the routine from returning this parameter. In this case, the application does not call rpc_string_free( ).

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

Description
The rpc_ns_group_mbr_inq_next( ) routine returns one member of the RPC group specified by the group_name parameter in the rpc_ns_group_mbr_inq_begin( ) routine.

An application can view all the members of an RPC group by calling the rpc_ns_group_mbr_inq_next( ) routine repeatedly. When all the group members have been viewed, this routine returns an rpc_s_no_more_members status. The returned group members are unordered.

On each call to this routine that returns a member name (as a global name), the RPC runtime allocates memory for the returned member_name. The application calls rpc_string_free( ) for each returned member_name string.

After viewing the RPC group's members, the application must call the rpc_ns_group_mbr_inq_done( ) routine to delete the inquiry context.

Permissions Required
You need read permission to the CDS object entry (the target group entry).

Return Values
No value is returned.
