           Summary: Consistent the size type. New logic to use.
           Product: Documentation
           Version: unspecified
    Kernel Version: 2.6.30.9
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: man-pages
        AssignedTo: documentation_man-pages-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org
        ReportedBy: vik-cfgfcfnPGrx6k2ZkT/Rh8A@public.gmane.org
        Regression: No


It is possible to do consistent the sizeof(). Just the size type be unsigned.
Next is sample:

unsigned long *p,*p2,length;
p=some_value;
p2=p;
length=sizeof(type_or_lvalue);
p+=length;
if(p<p2)
  catch_overrun...
*p=some_value2;

However the error codes is negative so it is hard to accept big size. Are the
race of system calls and kernel subroutines is different?
