bson_array_as_relaxed_extended_json - Man Page

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

• bson: A bson_t.
• length: An optional location for the length of the resulting string.

bson_as_relaxed_extended_json() encodes bson as a UTF-8 string in the Relaxed 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.

If successful, a newly allocated UTF-8 encoded string and length is set.

Upon failure, NULL is returned.

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_relaxed_extended_json (b, NULL);
printf ("Relaxed Extended JSON array: %s\n", str);
// Prints:
// Relaxed Extended JSON array: [ 1, "bar" ]
bson_free (str);
bson_destroy (b);
