NAME

       mongoc_client_select_server - mongoc_client_select_server()

SYNOPSIS

          mongoc_server_description_t *
          mongoc_client_select_server (mongoc_client_t *client,
                                       bool for_writes,
                                       const mongoc_read_prefs_t *prefs,
                                       bson_error_t *error) BSON_GNUC_WARN_UNUSED_RESULT;

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

       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.

PARAMETERS

       • 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 read  preference
         PRIMARY.

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

RETURNS

       A mongoc_server_description_t that must be freed with mongoc_server_description_destroy().
       If no suitable server is found, returns NULL and error is filled out.
