SYNOPSIS

6          size_t
7          bson_uint32_to_string (uint32_t value,
8                                 const char **strptr,
9                                 char *str,
10                                 size_t size);
11

PARAMETERS

13       • value: A uint32_t.
14
15       • strptr: A location for the resulting string pointer.
16
17       • str: A location to buffer the string.
18
19       • size: A size_t containing the size of str.

DESCRIPTION

22       Converts value to a string.
23
24       If  value  is  from 0 to 999, it will use a constant string in the data
25       section of the library.
26
27       If not, a string will be formatted using str and snprintf().
28
29       strptr will always be set. It will either point to str  or  a  constant
30       string. Use this as your key.
31

ARRAY ELEMENT KEY BUILDING

33       Each  element in a BSON array has a monotonic string key like "0", "1",
34       etc. This function is optimized for generating such string keys.
35
36          char str[16];
37          const char *key;
38          uint32_t i;
39
40          for (i = 0; i < 10; i++) {
41             bson_uint32_to_string (i, &key, str, sizeof str);
42             printf ("Key: %s\n", key);
43          }
44

RETURNS

46       The number of bytes in the resulting string.
