33 * lltostr -- convert long long to decimal string
34 *
35 * char *
36 * lltostr(value, ptr)
37 * long long value;
38 * char *ptr;
39 *
40 * Ptr is assumed to point to the byte following a storage area
41 * into which the decimal representation of "value" is to be
42 * placed as a string. Lltostr converts "value" to decimal and
43 * produces the string, and returns a pointer to the beginning
44 * of the string. No leading zeroes are produced, and no
45 * terminating null is produced. The low-order digit of the
46 * result always occupies memory position ptr-1.
47 * Lltostr's behavior is undefined if "value" is negative. A single
48 * zero digit is produced if "value" is zero.
