Splint with c++ code?

influ

Hi!

I'm new to splint and am trying to build some autocheck for our code.
Older splint output shall be compared with output after a fix to prevent new warnings being built in.

For most of the files I'm able to do that but a line I can't get around for example is

extern "C" void usr_INIT(){}

I learned that it's possible to use -Dnonstandardkeyword=, so in this case -Dextern= 'cuts' out the extern.

For the rest of the line a parse error is generated.
-Dextern=//
-Dextern='//'
-Dextern="//"
-Dextern=//
-Dextern "C"=
-Dextern "C"=
-D"extern "C""=

All don't work (expectable but at least I tried

Is it possible to mask that out at all?

Thx
Matt
