NAME

       ustrtol - Converts a string into an integer. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       long ustrtol(const char *s, char **endp, int base);

DESCRIPTION

       This  function  converts  the  initial part of `s' to a signed integer, setting `*endp' to
       point to the first unused character, if `endp' is not a NULL pointer. The `base'  argument
       indicates  what  base the digits (or letters) should be treated as. If `base' is zero, the
       base is determined by looking for `0x', `0X', or `0' as the first part of the string,  and
       sets  the  base  used  to  16, 16, or 8 if it finds one. The default base is 10 if none of
       those prefixes are found. Example:

          char *endp, *string = "456.203 askdfg";
          int number = ustrtol(string, &endp, 10);

RETURN VALUE

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