Ok.

To emulate the typical Un*x fork/dup/exec
- I need spawn to set its std{in,out,err} to something else,
so actually in spwan code :

pid_t spawn (const char *path, const int fdlen, const int fdarray[], 
 	const char *argv, const char **envp)
{
	...
	for (i = 0; i < fdlen; i++)
	{
		dup2(fdarray[i], i);
	}
	...
}

BTW, this merely a suggestion, I have no idea how spawn is implemented.

- When I spawn(), the parent goes on to its business right ?
You kinda hinted that It may not be the case witout
something call "start /m".

8-), Well with R. D. libsocket, I've already got the
ftp client working, and getting the rest of the clients should be
a question fo time. I don't know about the servers, to many unknowns.


I don't know if full DJGPP/libsocket support will make it to the
next release of inetutils, since it is a security fix release.
But probably hooks or at least the possibility to compile
some clients, like ftp, will be in.
