Ah, OK. I was confused how that was supposedly used. I suppose header-only C libs are somewhat a pain, as inline does not work the same way as in C++, and static may cause code bloat when inlining does not happen in multiple TUs.

View on HN

C Header-only libraries do not exist. It's just `#include "foo.c"` with extra steps.

`#include "foo.c"` would repeat the implementation in multiple object files which is both wasteful and, if not using static, create conflicting symbols.

You missed the "with extra steps".

  #define XXX_IMPL
  #include "xxx.h"

And

  #include "xxx.c"

Are exactly the same trash.

No they are not, the former allows you to include the header file in multiple .c files, the latter does not.
