Hi Rugxulo,

I looked at it again, the package is doing first a pipe() to establish
the communication and then a fork() to spawn the process in a new
daemon. Basically you can only use these functions if you have a multi-
tasking operating system. Eli is absolutely right here.

A pipe() function seems to be in the libsupp library now and also
there is a pipe() function in pth/pthreads but I do not understand
that implementation.
A fork() as fas as I know is not implemented with DJGPP. One may be
able to convert the fork() in the package to a pthread_create() but I
doubt that will work well in the end.

I will have to see what can be done here. I may just statically link
the functions of the to-be-spawned program with the main program and
convert the socket communication to function calls. However, this then
needs to be done for every new version of this package.

Georg
