Unable to print more than 4k character in TCL TK Client

[Rohit Kumar]

Hi All,

I am not able to print more than 4k characters in my TCL TK Client using puts command.

Can anyone suggest me the possibile reason behind it or any solution to overcome this problem.

Thanks in advance for your help.

There is probably a buffer limit on the puts statement. Do you really need to dump the entire buffer in one go? Could you dump it in several statements in smaller buffers?

Many thanks for your suggestion.
Yes I need to dump the entire buffer in one go.
Could you please let me know that how can we check the assigned buffer size in my case.

It will be something like this

set f [open "afile.bin" "wb"]
fconfigure $f -buffersize newsize
puts $f ...

For more info have a look at

Even with this the limit is 1 million - whether that is 1048576B or 1000000B, I don't know. I've never needed to change the buffer size. Sometimes documents say 1 million when they mean 1 Mega.
