Question on parsing a text file

[jared181]

Hi,
I have a question please.

I'm parsing a text file, and I'd like to detect when a certain Compilation Condition - i.e. #ifdef - begins.

The challenge is, that the condition can take any of the following patterns:

#ifdef (FLAG)

#if defined (FLAG)

#if (defined (FLAG))

(And perhaps I missed more)

I'd of course need to treat them all the same, as they are indeed the same.

How would you know to treat them all the same?

Thank you.
