ustrtol(3)                      Allegro manual                      ustrtol(3)

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'.
