Thanks, Hendrik - but guess what MS's own _popen function does? :)
Now I'd just have to figure out how to get a handle corresponding to my named pipe. The logging system I use launches an external viewer app when the 1st message is logged, and for some reason the named pipe is created by the viewer. (Presumably so that multiple clients can connect to it). The logging calls just use the pipe's name.
