PARAMETERS

  • 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.

This function returns a newly allocated mongoc_cursor_t that should be freed with mongoc_cursor_destroy() when no longer in use. The returned mongoc_cursor_t is never NULL, even on error. The user must call mongoc_cursor_next() on the returned mongoc_cursor_t to execute the initial command.

Cursor errors can be checked with mongoc_cursor_error_document(). It always fills out the bson_error_t if an error occurred, and optionally includes a server reply document if the error occurred server-side.

WARNING:

Failure to handle the result of this function is a programming error.
