I'm using APR as portability library for my program.
I'm accepting a network connection in the parent and later I spawn a
child process passing the OS file descriptor (e.g. 4) to the child

I construct an apr socket in the child process from the passed file
descriptor number (e.g. 4). Later when I try to get a remote address, I'm
getting an error that the given file descriptor is not a socket. I'm also
unable to write to the mentioned socket (no data arives to the client).

The same program is working fine on Linux. So I guess that there is a
strange 'trick' how to make file descriptor inheriting work. Any hint?

Thanks and best regards,
