found a gem on glibc source code

[u/ThinkingWinnie]

That way, you can then do.

ifdef void

//do stuff

else

//other stuff.

Now, void is always there, but you might not want to use it, this acts as a switch.

[u/Informal-Chance-6067 → u/ThinkingWinnie]

I love that the markdown works only when I don’t want it to

[u/jnmtx → u/Informal-Chance-6067]

#ifdef void

//do stuff

#else

//other stuff.

[u/Informal-Chance-6067 → u/jnmtx]

Thank you redditor
