bson_uint32_to_string (uint32_t value,
                       const char **strptr,

  • value: A uint32_t.
  • strptr: A location for the resulting string pointer.
  • str: A location to buffer the string.
  • size: A size_t containing the size of str.

Converts value to a string.

If value is from 0 to 999, it will use a constant string in the data section of the library.

If not, a string will be formatted using str and snprintf().

strptr will always be set. It will either point to str or a constant string. Use this as your key.

Each element in a BSON array has a monotonic string key like "0", "1", etc. This function is optimized for generating such string keys.

char str[16];
const char *key;
uint32_t i;
for (i = 0; i < 10; i++) {
   bson_uint32_to_string (i, &key, str, sizeof str);
   printf ("Key: %s\n", key);
}


The number of bytes in the resulting string.
