       Choose a server for an operation, according to the logic described in the Server Selection

       Use this function only for building a language  driver  that  wraps  the  C  Driver.  When
       writing applications in C, higher-level functions automatically select a suitable server.


       · client: A mongoc_client_t.

       · for_writes: Whether to choose a server suitable for writes or reads.

       · prefs:  An  optional  mongoc_read_prefs_t.  If  for_writes  is true, prefs must be NULL.
         Otherwise, use prefs to customize server  selection,  or  pass  NULL  to  use  the  read
         preference configured on the client.

       · error: An optional location for a bson_error_t or NULL.


       A  mongoc_server_description_t  that must be freed with mongoc_server_description_destroy.
