SYNOPSIS¶

char *
bson_array_as_canonical_extended_json (const bson_t *bson, size_t *length);

PARAMETERS¶

DESCRIPTION¶

bson_array_as_canonical_extended_json() encodes bson as a UTF-8 string in Canonical Extended JSON. The outermost element is encoded as a JSON array ([ ... ]), rather than a JSON document ({ ... }). See MongoDB Extended JSON format for a description of Extended JSON formats.

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_canonical_extended_json (b, NULL);
printf ("Canonical Extended JSON array: %s\n", str);
// Prints:
// Canonical Extended JSON array: [ { "$numberInt" : "1" }, "bar" ]
bson_free (str);
bson_destroy (b);
