c++ - TCL C API Create and Register new Channel -

i use tcl 8.6(windows) , can't register , use new channels

std::ofstream file("1.txt");  tcl_channel kanal = tcl_createchannel(type, "mychann", file, tcl_writable); tcl_registerchannel(interp, kanal);  file.close(); 

and type

tcl_channeltype* type = new tcl_channeltype(); type->closeproc = closeproc; type->inputproc = inputproc; type->outputproc = outputproc; type->typename = "my own chann"; type->version = tcl_channel_version_2; 

functions simply, have std::cout

i run interpreter script

"chan puts mychan whatever" 

and nothing happend, no errors interpreter, no output(console, file). dont know how bite this, first goal, create new chanel , use it, second replace tcl_stdout own channel(it can std::ofstream), when run interpreter with

"puts whatever" 

that string go std::ofstream

probably did not flush output.

this can done with

flush mychan 

you can configure channel flush @ end of line or whenever written it:

chan configure mychan -buffering line 

(or none). stdout default configured -buffering line
