bson_as_canonical_extended_json - bson_as_canonical_extended_json()

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


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

The bson_as_canonical_extended_json() encodes bson as a UTF-8 string in the canonical MongoDB Extended JSON format.

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.

char *str = bson_as_canonical_extended_json (doc, NULL);
printf ("%s\n", str);
bson_free (str);
