mongoc_database_t *
mongoc_database_copy (mongoc_database_t *database);

• database: A mongoc_database_t.

Performs a deep copy of the database struct and its configuration. Useful if you intend to call mongoc_database_set_write_concern, mongoc_database_set_read_prefs, or mongoc_database_set_read_concern, and want to preserve an unaltered copy of the struct.

This function does not copy the contents of the database on the MongoDB server; use the copydb command for that purpose.

A newly allocated mongoc_database_t that should be freed with mongoc_database_destroy() when no longer in use.
