NAME

6       bson_as_json - bson_as_json()
7

SYNOPSIS

9          char *
10          bson_as_json (const bson_t *bson, size_t *length);
11

PARAMETERS

13       · bson: A bson_t.
14
15       · length: An optional location for the length of the resulting string.
16

DESCRIPTION

18       The  bson_as_json()  function shall encode bson as a UTF-8 string using
19       libbson's  legacy  JSON  format.  This  function   is   superseded   by
20       bson_as_canonical_extended_json()  and bson_as_relaxed_extended_json(),
21       which use the same MongoDB Extended JSON format as  all  other  MongoDB
22       drivers.
23
24       The  caller  is  responsible  for  freeing  the resulting UTF-8 encoded
25       string by calling bson_free() with the result.
26
27       If non-NULL, length will be set to the length of the result in bytes.
28

RETURNS

30       If successful, a newly allocated UTF-8 encoded  string  and  length  is
31       set.
32
33       Upon failure, NULL is returned.
34

EXAMPLE

36          #include <bson/bson.h>
37
38          int main ()
39          {
40             bson_t bson;
41             char *str;
42
43             bson_init (&bson);
44             BSON_APPEND_UTF8 (&bson, "0", "foo");
45             BSON_APPEND_UTF8 (&bson, "1", "bar");
46
47             str = bson_as_json (&bson, NULL);
48             /* Prints
49              * { "0" : "foo", "1" : "bar" }
50              */
51             printf ("%s\n", str);
52             bson_free (str);
53
54             bson_destroy (&bson);
55          }
