BSON_AS_LEGACY_EXTENDED_JSON(3) libbson BSON_AS_LEGACY_EXTENDED_JSON(3) SYNOPSIS char * bson_as_legacy_extended_json (const bson_t *bson, size_t *length) PARAMETERS • bson: A bson_t. • length: An optional location for the length of the resulting string. DESCRIPTION bson_as_legacy_extended_json() encodes bson as a UTF-8 string using libbson's Legacy Extended JSON. This function is superseded by bson_as_canonical_extended_json() and bson_as_relaxed_extended_json(), which use the same MongoDB Extended JSON format as all other MongoDB drivers. The caller is responsible for freeing the resulting UTF-8 encoded string by calling bson_free() with the result. If non-NULL, length will be set to the length of the result in bytes. RETURNS If successful, a newly allocated UTF-8 encoded string and length is set. Upon failure, NULL is returned. EXAMPLE bson_t *b = BCON_NEW ("foo", BCON_INT32 (123)); char *str = bson_as_legacy_extended_json (b, NULL); printf ("Legacy Extended JSON: %s\n", str); // Prints: // Legacy Extended JSON: { "foo" : 123 } bson_free (str); bson_destroy (b); AUTHOR MongoDB, Inc COPYRIGHT 2009-present, MongoDB, Inc. 1.30.2 Apr 12, 2025 BSON_AS_LEGACY_EXTENDED_JSON(3)
