DESCRIPTION The bson_append_document_begin() function shall begin appending a sub-docu- ment 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 Returns true if the operation was applied successfully.
