Error trying to define a 1,024-bit (128 Byte) Bit Field

Question

I would like to define a large bitfield for the purpose of quickly monitoring the status a very large structure of elements. Here is what I have so far:

#define T         


        

Answer 1

Bit fields must fit within a single int, you can't use arbitrary sizes. Honestly the ANSI bitfield implementation is kinda broken. It misses a lot of other stuff too, like control over padding and layout that real-world applications usually need. I'd consider writing some macros or accessor functions to abstract the larger sizes and giving up on the bitfield syntax.
