does anyone actually use header guards anymore in personal c++ projects lol

Follow

@deadbeef Only to prevent errors about duplication of entities at either compile or link time.

@rmerriam " once" directive seems to be supported by most compilers nowadays. I've never had to use manual include guards, though again, none of the projects I've worked on are really that big.

@rmerriam Could be some edge cases where once doesn't work.

@deadbeef

I consider both techniques to be guards. Generally, I use the pragma.

@rmerriam True, although by "header/include guard" I meant the "old style" using , , etc. And yeah, pragma is definitely more convenient.
