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'.
