I am having a small debugging issue using C++ and TCF ( Target communication framework) in Eclipse IDE.
Eclipse refuses to override / download running code with the latest build.



So I need to remove current running (source) version of the code on target system. Crude but it does the job I need.



I was hoping to use "system" call and have its usage partially figured out.
The "problem" is - I do not know HOW to write a C++ code to emulate terminal.



In my "main: I have



system("sudo -i"); 


that gets me a response on TCF terminal



root@ARM:~#



where I keep my debugged applications.



and I can manually input there , no problem



The issue is - how do I do it in C++ code ?



cout <<"ls"



does not work.



I am planning to have small C++ app dedicated to the task of removing the older version of the source code.
I can do this manually in running target terminal, however I will need a the ability to "emulate" the target terminal ( in C++ code ) in future debugging.
