16 This function converts the initial part of `s' to a signed integer,
17 setting `*endp' to point to the first unused character, if `endp' is
18 not a NULL pointer. The `base' argument indicates what base the digits
19 (or letters) should be treated as. If `base' is zero, the base is
20 determined by looking for `0x', `0X', or `0' as the first part of the
21 string, and sets the base used to 16, 16, or 8 if it finds one. The
22 default base is 10 if none of those prefixes are found. Example:
23
24 char *endp, *string = "456.203 askdfg";
25 int number = ustrtol(string, &endp, 10);
26
28 Returns the string converted as a value of type `long int'. If nothing
29 was converted, returns zero with `*endp' pointing to the beginning of
30 `s'.
