mongoc_database_set_write_concern - Man Page

void
mongoc_database_set_write_concern (mongoc_database_t *database,
                                   const mongoc_write_concern_t *write_concern);

This function sets the write concern to use on operations performed with database. Collections created with mongoc_database_get_collection() after this call will inherit this write concern.

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.

• database: A mongoc_database_t.
• write_concern: A mongoc_write_concern_t.
