what about #defining them so they trigger an error?
#define ntohl error() won't work, a g_ntohl would match as well.
I'm not sure that's true. Have you actually tried?
a macro definition is different from a simple define, #define ntohl()
will *not* affect any g_ntohl() calls! -> no problem here!
FWIW, Samba3 is doing something similar for C++ reserved words:
(http://viewcvs.samba.org/cgi-bin/viewcvs.cgi/branches/SAMBA_3_0_RELEASE/source/include/includes.h?rev=19018&view=markup)
- --- snip ---
/* only do the C++ reserved word check when we compile
to include --with-developer since too many systems
still have comflicts with their header files (e.g. IRIX 6.4) */
#if !defined(__cplusplus) && defined(DEVELOPER)
#define class #error DONT_USE_CPLUSPLUS_RESERVED_NAMES
#define private #error DONT_USE_CPLUSPLUS_RESERVED_NAMES
#define public #error DONT_USE_CPLUSPLUS_RESERVED_NAMES
#define protected #error DONT_USE_CPLUSPLUS_RESERVED_NAMES
#define template #error DONT_USE_CPLUSPLUS_RESERVED_NAMES
#define this #error DONT_USE_CPLUSPLUS_RESERVED_NAMES
#define new #error DONT_USE_CPLUSPLUS_RESERVED_NAMES
#define delete #error DONT_USE_CPLUSPLUS_RESERVED_NAMES

This is a simple approach which seem to be also working for function
declarations :-)
[...]
So with the current #include sequence this won't work!
Any ideas?
Perl is built for this kind of thing. :-)
It requires an extra step, but the code to do it is quite easy, see
attached. This program has 2 lists: a list of prohibited APIs that must
not be used (or the program will return an error) and a list of
deprecated APIs that, if they are used, only generate a warning.
Does Subversion have the concept of a check-in trigger? E.g., before
accepting the check-in it runs a script and if the script returns an
error, the check-in fails? Could be done there, though that's a bit
aggressive ;-).
Or "make codecheck" or something else...
Of course the lists I put are just some basics for testing. And maybe
the lists need to be different for dissectors vs. core Wireshark, etc.,
but the concept is there. I even put a Copyright notice in case it's a
good enough start. :-)
