SYNOPSIS

          char *
          bson_array_as_relaxed_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_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 <https://github.com/mongodb/specifications/blob/master/source/extended-json/
       extended-json.md> 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_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);
