[fpc-pascal] How to translate this union ?

[Ludo Brands]

Forget my previous reply. I found the original header file on sourceforge. 
 
I have alse a better understanding now of what the code is supposed to do:
in case DOCUMENTATION_ONLY is not defined,  a reference to, for example,
su_sockaddr_u.su_family will be subsstituted by
su_sockaddr_u.susa.sa_family. 
You could use macros and do a {$define su_family:=susa.sa_family} with the
following limitations:
- if you have variables or other record members named su_family, not part of
the su_sockaddr_u record, they will be renamed also. 
- it works only for the units that include your .inc file.

Can you post the original c code? You point to a file that seems to be a
reworked output from h2pas. As it is now, it indeed doesn't make any sense.
I would think the su_len,su_family,su_port should make up a record but they
aren't.
 
I suggest you move the #defines inside the union declaration to somewhere
before the union declaration. It'll double up the ifdef's but make the code
so much more readable.

Hello list,

I'm trying to translate the following
<https://github.com/ik5/sofia-sip/blob/master/src/lib/sui.inc#L199> union to
Pascal, but I do not understand it, and so does h2pas.
How to translate it ?

Thanks,

Ido
