This function is superseded by mongoc_collection_command_with_opts(), mongoc_collection_read_command_with_opts(), mongoc_collection_write_command_with_opts(), and mongoc_collection_read_write_command_with_opts().

This function is not considered a retryable read operation.


  • collection: A mongoc_collection_t.

  • flags: A mongoc_query_flags_t.

  • skip: A uint32_t with the number of documents to skip or zero.

  • limit: A uint32_t with the max number of documents to return or zero.

  • batch_size: A uint32_t with the number of documents in each batch or zero. Default is 100.

  • command: A bson_t containing the command to execute.

  • fields: A bson_t containing the fields to return or NULL. Not all commands support this option.

  • read_prefs: An optional mongoc_read_prefs_t. Otherwise, the command uses mode MONGOC_READ_PRIMARY.


A mongoc_cursor_t.

The cursor should be freed with mongoc_cursor_destroy().
