17 bson_string_t is an abstraction for building strings. As chunks are
18 added to the string, allocations are performed in powers of two.
19
20 This API is useful if you need to build UTF-8 encoded strings.

25 str = bson_string_new (NULL);
26 bson_string_append_printf (str, "%d %s %f\n", 0, "some string", 0.123);
27 printf ("%s\n", str->str);
28
29 bson_string_free (str, true);

31 TIP:
32 You can call bson_string_free() with false if you would like to take
33 ownership of str->str. Some APIs that do this might call return
34 bson_string_free (str, false); after building the string.
