 NAME

   rpc_ns_binding_select - Returns a binding handle from a list of
                           compatible server binding handles

   Used by client applications.

 SYNOPSIS

   #include <dce/rpc.h>

   void rpc_ns_binding_select( rpc_binding_vector_t *binding_vec,
                               rpc_binding_handle_t *binding,
                               unsigned32 *status );

 PARAMETERS

   Input/Output

   binding_vec
       Specifies the vector of compatible server binding handles from
       which a binding handle is selected. The returned binding vector
       no longer references the selected binding handle (returned
       separately in the binding parameter).

   Output

   binding
       Returns a selected server binding handle.

   status
       Returns the status code from this routine, which 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_no_more_bindings
                   No more bindings.

 DESCRIPTION

   The rpc_ns_binding_select() routine randomly chooses and returns a
   server binding handle from a vector of server binding handles.

   Each time the client calls rpc_ns_binding_select(), the routine
   returns another binding handle from the vector.

   When all of the binding handles are returned from the vector, the
   routine returns a status code of rpc_s_no_more_bindings and
   returns the value NULL in binding.

   The select operation allocates storage for the data referenced by the
   returned binding parameter.  When a client finishes with the binding
   handle, it calls rpc_binding_free() to deallocate the storage.  Each
   call to the rpc_ns_binding_select() routine requires a corresponding
   call to rpc_binding_free().

   Instead of using this routine, client applications can select a
   binding handle according to their specific needs.  In this case the
   rpc_binding_to_string_binding() and rpc_string_binding_parse()
   routines are useful to the applications since the routines work
   together to extract the individual fields of a binding handle for
   examination.

   Permissions Required

   No permissions are required.

 RETURN VALUES

   No value is returned.
