a part of stdio, this filehandle is opened by default for each application making use of the stdio package of code.
This output file may correspond to a disk file, pipe, terminal device, or other construct.
To refer to this output filehandle in Tcl, use the string stdout when using puts .
Tcl 8.3 had a problem on stdout, when it was redirected to a file. The problem was that every buffer write caused a flush of the disk cache. The workaround in 8.3 was to do (once, at beginning of script):
fconfigure stdout -buffering full -buffersize 262144
so that there were few disk writes performed. (Thanks KBK and the Tcl chatroom for the quick answer! RS)
LV anyone want to address the situation with stdio and Windows? Are the file handles available by default? What do you have to do to see the output going to stdout?
