>Number: 2752
>Category: bin
>Synopsis: NULL is used instead of 0 many places
>Confidential: no
>Severity: non-critical
>Priority: medium
>Responsible: freebsd-bugs
>State: open
>Class: sw-bug
>Submitter-Id: current-users
>Arrival-Date: Mon Feb 17 01:20:02 PST 1997
>Last-Modified:
>Originator: Arne Henrik Juul
>Organization:
Norwegian University of Technology and Science
>Release: FreeBSD 2.2-GAMMA i386
>Environment:
Note that this was tested with a make world on 2.2-GAMMA, but the
patches applies (with a little fuzz) to 3.0-current as well. I
can generate a clean set for 3.0-current on request.
>Description:
Many places in the code NULL is used in integer context, where
plain 0 should be used. This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.
>How-To-Repeat:
#define NULL ((void *)0) in various include files and recompile
the world.
>Fix:
Appy following patch. This changes NULL to 0 most places
but to '\0' in character context, to be more stylistically
correct.
