13 double ustrtod(const char *s, char **endp);
14
16 This function converts as many characters of `s' that look like a
17 floating point number into one, and sets `*endp' to point to the first
18 unused character, if `endp' is not a NULL pointer. Example:
19
20 char *endp, *string = "456.203 askdfg";
21 double number = ustrtod(string, &endp);
22
24 Returns the string converted as a value of type `double'. If nothing
25 was converted, returns zero with *endp pointing to the beginning of s.
