Description

bson_uint32_to_string - bson_uint32_to_string()

size_t
bson_uint32_to_string (uint32_t value,
const char **strptr,
char *str,
size_t size);

	•		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.
