http://purl.org/tcl/home/man/tcl8.4/TclCmd/fcopy.htm : '''fcopy''' ''inchan outchan'' ?'''-size''' ''size''? ?'''-command''' ''callback''? '''fcopy''' provides the developer the ability to copy data from an input channel to an output channel, either synchronously or in the background, using [fileevent]s to schedule activity. For copying a file from one place in a filesystem to another see also [file copy]. <> [LV] Does anyone have some sample code to demonstrate some tcl [best practices] concerning writing async code using fcopy to copy files ? Maybe for instance the example could loop through 3 machines doing an fcopy of a file like /tmp/motd? What I'm after is some examples of the type of code doing error checking for things like machines not available, out of disk space, etc - all the sort of things that if one is trying to write a 'safe' application one would do. ---- [LV] In April, 2005, on comp.lang.tcl, a thread titled ''fcopy problem'' was discussing problems using fcopy on large binary files between channels. The fcopy appeared to be losing bytes. The original poster was using ''-encoding binary'', because the documentation said that this '''will then assign no interpretation to the data in the file and simply read or write raw bytes'''. However, [DKF] suggested changing to use ''-translation binary'' instead. The original poster followed up that making that change indeed sorted out his problem. ---- [dzach] 2006-5-8 Hmm... After spending a day trying to make a bidirectional copy between two open sockets, I wonder if something like '''fcopy sock1 sock2 -bidirectional 1 -command script''' is possible with fcopy as it stands today. So, a day later, here is [fconnect], kind of a bidirectional ''fcopy''. <> ---- !!!!!!
