[tcljava-dev] Channel mapping for stdin, stdout, etc.

[David L. Smith-U. <da...@ig...>]

Hmmm....Looking back through the mailing list archive there was a bug 
221678 which asserts that the channels for standard in, out and err should 
have dual names stdin/file0 stdout/file1 stderr/file2.  It seems as though 
there's a problem with channels having dual names and error reporting.

However, there's a deeper problem and that is that there is no way to have 
stdin, stdout and stderr attach to anything except System.in, System.out 
and System.err since the StdChannel implementation is hardwired into TclIO.

Since I want to imbed Tcl inside of my shell and control where the I/O goes 
(and I'd like to be able to have it go different places for each Tcl 
instance so simply setting System.in, etc. doesn't work for me) I'd like to 
undo the hardwiring inside of TclIO and let the channel assignment be 
overriden.

Also, is there a requirement that stdin == file0, etc?  Is this an alias?

Cheers,
Dave
