It's quite complicated. Soes it need to be? :-)

Is this C or C++ source code? I always thought // was C++

Where's my return datatype? And when (int) is the default,
where is my return statement? :-)

If you need type conversion, you can't do this in the
function's declaration. You need to perform this with
the call. The function would rather start as

	void skipTags(char *s)

and then be called with the correct pointer

	char *bla;
	...
	skipTags(bla);

Instead of pointer arithmethics, which is one of the
ultimate skills in C, you could use an iterator from 0
to strlen(s).

I think the code above is just part of a bigger mechanism.
Looks like you want to "shift" the character pointer to
override any <...> segments, and then let some other
parts do something more, right?
