WRITE CONCERN LEVELS
Set the write concern level with mongoc_write_concern_set_w() <>.
| MONGOC_WRITE_CONCERN_W_DEFAULT (1) | By default, writes block awaiting acknowledgement from MongoDB. Acknowledged write concern allows clients to catch network, duplicate key, and other errors. |
| MONGOC_WRITE_CONCERN_W_UNACKNOWLEDGED (0) | With this write concern, MongoDB does not acknowledge the receipt of write operation. Unacknowledged is similar to errors ignored; however, mongoc attempts to receive and handle network errors when possible. |
| MONGOC_WRITE_CONCERN_W_MAJORITY (majority) | Block until a write has been propagated to a majority of the nodes in the replica set. |
| n | Block until a write has been propagated to at least n nodes in the replica set. |
