SYNOPSIS¶

char *
bson_array_as_legacy_extended_json (const bson_t *bson, size_t *length)

PARAMETERS¶

DESCRIPTION¶

bson_array_as_legacy_extended_json() encodes bson as a UTF-8 string using libbson's Legacy Extended JSON. The outermost element is encoded as a JSON array ([ ... ]), rather than a JSON document ({ ... }). This function is superseded by bson_array_as_canonical_extended_json() and bson_array_as_relaxed_extended_json(), which use the same MongoDB Extended JSON format as all other MongoDB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 ("0", BCON_INT32 (1), "1", BCON_UTF8 ("bar"));
// The document for an array is a normal BSON document with integer values for the keys, starting with 0 and
// continuing sequentially.
char *str = bson_array_as_legacy_extended_json (b, NULL);
printf ("Legacy Extended JSON array: %s\n", str);
// Prints:
// Legacy Extended JSON array: [ 1, "bar" ]
bson_free (str);
bson_destroy (b);
