SYNOPSIS

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

PARAMETERS

       • bson: A bson_t.

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

DESCRIPTION

       bson_as_legacy_extended_json() encodes bson as a UTF-8 string using libbson's Legacy Extended JSON.  This
       function  is  superseded  by bson_as_canonical_extended_json() and bson_as_relaxed_extended_json(), which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 ("foo", BCON_INT32 (123));
          char *str = bson_as_legacy_extended_json (b, NULL);
          printf ("Legacy Extended JSON: %s\n", str);
          // Prints:
          // Legacy Extended JSON: { "foo" : 123 }
          bson_free (str);
          bson_destroy (b);
