Ayman asks
<<How is a variant record implemented in Ada. I need to write a variant
record and then be able to read its contents and copy them into a C
union.>>
This is a misformed question. There is no general answer, you can only
ask how a variant record is implemented in a given implementation of
Ada on a particular machine with a particular operating system, not
in general for the ada language.
However, there is probably a nice answer for you, which is look up
pragma Unchecked_Union, it is *specifically* intended for interfacing
to C unions.
