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
