Synopsis

bool
bson_append_document_begin (bson_t *bson,
                            const char *key,
                            int key_length,
                            bson_t *child);

Parameters

  • bson: A bson_t.
  • key: An ASCII C string containing the name of the field.
  • key_length: The length of key in bytes, or -1 to determine the length with strlen().
  • child: An uninitialized bson_t to be initialized as the sub-document.

Description

The bson_append_document_begin() function shall begin appending a sub-document to bson. Use child to add fields to the sub-document. When completed, call bson_append_document_end() to complete the element.

child MUST be an uninitialized bson_t to avoid leaking memory.

Returns

true if the operation was applied successfully, otherwise false and bson should be discarded.
