### Definitions
|
||||
|
||||
`#define` the following C preprocessor macros before including `<kernaux.h>` and
|
||||
`<kernaux/*.h>` files. They have effect on your code, not the library code.
|
||||
|
||||
* `KERNAUX_ACCESS_PRIVATE` - disable access modifier "private". Don't do this!
|
||||
* `KERNAUX_ACCESS_PROTECTED` - disable access modifier "protected". Only do this
|
||||
in a file where you implement an inherited type.
|
||||
* `KERNAUX_BITFIELDS` - enable bitfields in packed structs. It doesn't follow
|
||||
the C standard and may be incompatible with some compilers.
