But in this case, the spawned program that is your processes's direct child might be the program you wanted, or might be a handler daemon, depending upon whether there was one already running. It's a minor irritant having this be inconsistent like this. xmms2 requires a common daemon, so when you run xmms2cli or whatever, it launches xmms2d if there isn't one already running. As a child. And the daemon gets reparented. So it's transarent to any sort of script that might be using xmms2cli. Mono gets this backwards. For example, something not _too_ strange in the land of scripting: my_program wait There might be some need for my_program to do something stupid that requires this instead of just "my_program". If another mono task gets launched (seperately) while my_program (and its spawn) are doing their thing, ``wait'' will wait until every Mono program is done. > I am driven to ask, though, is this actually using $HOME or is it > calling getpwuid(getuid()) to find your home directory? I did not mean the env variable. I assume it uses the normal calls. Mono is somewhat sound in terms of technology, it just has completely stupid design. -joshThere's stuff above here
