AFAIK: mostly dependent on endianess of the arch.

There was an interesting discussion on that in the mse forum (for the

It's not an initialization, it's a struct with bitfields. FPC currently
does not support C-compatible bitfield packing. To get a record with
equal alignment and size you can declare it as "record data: cuint;
end;", but

Thanks Jonas!
One more question. Why is it that there is no portable way to access the
bitfields? Is that because of endian issues, or is there more to it?
What about declaring the bitfields in a bitpacked record as "array of
boolean"?

Hi,
What would be the equivalent of the following struct definition in C?
typedef struct MyStruct
{
unsigned a :6;
unsigned b :15;
unsigned c:11;
}MyStruct;
I imagine this is some sort of struct initialization. Is thi spossible
in FPC as well, or what is the best alternative?
