bson_as_canonical_extended_json3

Parameters

Overview

bson_as_canonical_extended_json() encodes bson as a UTF-8 string in the Canonical Extended JSON. 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.

Examples

bson_t *b = BCON_NEW ("foo", BCON_INT32 (123));
char *str = bson_as_canonical_extended_json (b, NULL);
printf ("Canonical Extended JSON: %s\n", str);
// Prints:
// Canonical Extended JSON: { "foo" : { "$numberInt" : "123" } }
bson_free (str);
bson_destroy (b);
