NAME
rpc_ns_mgmt_binding_unexport - Removes multiple binding handles, or
object UUIDs, from an entry in the
name service database
Used by management applications.
SYNOPSIS
#include <dce/rpc.h>
void rpc_ns_mgmt_binding_unexport( unsigned32 entry_name_syntax,
unsigned_char_t *entry_name,
rpc_if_id_t *if_id,
unsigned32 vers_option,
uuid_vector_t *object_uuid_vec,
unsigned32 *status );
PARAMETERS
Input
entry_name_syntax
An integer value that specifies the syntax of the
entry_name parameter. To use the syntax specified
in the RPC_DEFAULT_ENTRY_SYNTAX logical name, provide
rpc_c_ns_syntax_default.
entry_name
Specifies an entry name whose binding handles or object UUIDs are
removed. This can be either the global or cell-relative name.
if_id
Specifies an interface identifier for the binding handles to be
removed from the name service database. The value NULL indicates
that no binding handles are removed (only object UUIDs are
removed).
vers_option
Specifies how the rpc_ns_mgmt_binding_unexport() routine uses the
vers_major and the vers_minor fields of the if_id parameter.
The following table presents the accepted values for this parameter:
Uses of vers_major and vers_minor fields of if_id
_____________________________________________________________________
Value Description
_____________________________________________________________________
rpc_c_vers_all Unexports (removes) all bindings
for the interface UUID in if_id,
regardless of the version
numbers. For this value,
specify 0 (zero) for both the
major and minor versions in if_id.
rpc_c_vers_compatible Removes those bindings for the
interface UUID in if_id with the
same major version as in if_id,
and with a minor version greater
than or equal to the minor ver-
sion in if_id.
rpc_c_vers_exact Removes those bindings for the
interface UUID in if_id with the
same major and minor versions as
in if_id.
rpc_c_vers_major_only Removes those bindings for the
interface UUID in if_id with the
same major version as in if_id
(ignores the minor version).
For this value, specify 0 (zero)
for the minor version in if_id.
rpc_c_vers_upto Removes those bindings that
offer a version of the specified
interface UUID less than or
equal to the specified major and
minor version. (For example, if
if_id contains V2.0 and the name
service entry contains binding
handles with the versions V1.3,
V2.0, and V2.1, the rpc_ns_mgmt-
_binding_unexport() routine
removes the binding handles with
V1.3 and V2.0.)
object_uuid_vec
Specifies a vector of object UUIDs to be removed from the name
service database. The application constructs this vector. The
value NULL indicates that no object UUIDs are removed (only
binding handles are removed).
Output
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_entry_not_found
Name service entry not found.
rpc_s_incomplete_name
Incomplete name.
rpc_s_interface_not_found
Interface not found.
rpc_s_invalid_name_syntax
Invalid name syntax.
rpc_s_invalid_vers_option
Invalid version option.
rpc_s_name_service_unavailable
Name service unavailable.
rpc_s_no_ns_permission
No permission for name service operation.
rpc_s_not_all_objs_unexported
Not all objects unexported.
rpc_s_nothing_to_unexport
Nothing to unexport.
rpc_s_not_rpc_entry
Not an RPC entry.
rpc_s_unsupported_name_syntax
Unsupported name syntax.
DESCRIPTION
The rpc_ns_mgmt_binding_unexport() routine allows a management
application to unexport (that is, remove) one of the following from
an entry in the name service database:
+ All the binding handles for a specified interface UUID, qualified
by the interface version numbers (major and minor).
+ One or more object UUIDs of resources.
+ Both binding handles and object UUIDs of resources.
A management application can remove an interface and objects in a
single call to this routine, or it can remove them separately.
If the rpc_ns_mgmt_binding_unexport() routine does not find any
binding handles for the specified interface, the routine returns
an rpc_s_interface_not_found status and does not remove the object
UUIDs, if any are specified.
If one or more binding handles for the specified interface are found
and removed without error, rpc_ns_mgmt_binding_unexport() removes the
specified object UUIDs, if any.
If any of the specified object UUIDs are not found,
rpc_ns_mgmt_binding_unexport() returns the rpc_not_all_objs_unexported
status code.
A management application, in addition to calling this routine, also
calls the rpc_mgmt_ep_unregister() routine to remove any servers that
have registered with the local endpoint map.
Use this routine with caution, only when you expect a server to be
unavailable for an extended time; for example, when it is permanently
removed from service.
Additionally, keep in mind that name service databases are designed to
be relatively stable. In replicated name service databases, frequent
use of the rpc_ns_binding_export() and rpc_ns_mgmt_binding_unexport()
routines causes the name service to remove and replace the same entry
repeatedly, and can cause performance problems.
Permissions Required
You need both read permission and write permission to the CDS object
entry (the target name service entry).
RETURN VALUES
No value is returned.
