NAME

ustrtod - Converts a string into a floating point number. Allegro game programming library.

SYNOPSIS

#include <allegro.h>

double ustrtod(const char *s, char **endp);

DESCRIPTION

This function converts as many characters of `s' that look like a floating point number into one, and sets `*endp' to point to the first unused character, if `endp' is not a NULL pointer. Example:

   char *endp, *string = "456.203 askdfg";
   double number = ustrtod(string, &endp);

RETURN VALUE

Returns the string converted as a value of type `double'. If nothing was converted, returns zero with *endp pointing to the beginning of s.
