There’s also a directive (don’t have code in front of me) that you can do at file level that will cause all subsequent struct defs to be packed…

#push(pragma(pack(0)) ??

I’ve done a lot of direct register access in C this way. I do like Zigs ability to just define the different sizes though.

It’s MS(V)C syntax, now supported by GCC and Clang as well:

  #pragma pack(push)
  #pragma pack(1)
  /* ... */
  #pragma pack(pop)

The first two lines can also be condensed into

  #pragma pack(push, 1)
