       • client: A mongoc_client_t.

       • write_concern: A mongoc_write_concern_t.

          void
          mongoc_client_set_write_concern (mongoc_client_t *client,
                                           const mongoc_write_concern_t *write_concern);

       Sets  the  write  concern for the client. This only affects future operations, collections, and databases
       inheriting from client.

       The  default  write  concern  is  MONGOC_WRITE_CONCERN_W_DEFAULT:  the  driver  blocks   awaiting   basic
       acknowledgement  of  write  operations  from  MongoDB.  This  is  the correct write concern for the great
       majority of applications.

       It is a programming error to call this function on a  client  from  a  mongoc_client_pool_t.  For  pooled
       clients, set the write concern with the MongoDBURI instead.
