tool to check multiple inclusion of header file

[techBoy]

I am looking for a tool which can scan my source code and tell me if a
header file gets included more then once in a sequence of source file
or header files. Can some one guide me to such a tool !!

This is off-topic here, but...

<OT>
Did you consider using `grep` to find all occurrences of #include lines
(`grep` can tell you which files they belong to, and/or their total
count, as well)? Further clever processing of the `grep` output should
be able to give you the answer you want.

There may be better ways/specialised tools, but I'm not aware of them.

May I ask why you want to do this? If it's because you're getting circular
references, you should perhaps use the following technique ...

#ifndef MY_HEADER_H
#define MY_HEADER_H

// MY_HEADER_H stuff here.

#endif

If it's not for that - just through curiosity, I'd be interested in knowing
the 'why'.

gcc preprocessor source code may give some insight

You can look for check, cproto, cdecl, ctool, cxref, etc. I don't recall
which one does what. Most of these are available from comp.sources.unix or
DECUS. But, you can Google them.

comp.sources.unix, cxref is in volume1:

Yaa a header gurad is a good idea, I am already using that. Trying to
bring dwon my compilation time. So wanted to eliminate this aspect
first, and see to it that a header file doesn't get included more than
once.

Quoting context is essential, especially so when you make so many
spelling mistakes that it's hard to figure out what you're saying. Read
