Recently on the dig command lineProgram, Similar to netsh in windows. Summary of some tips.

 

If you want to create a command line program that does not return data, you have to use the dead cycle program to wait for the input using the dead loop program.

The general handling method is as follows:

While (1)

{

...

CCH = _ getch ();

_ Putch (CCH );

...

}

Accept one character at a time and handle it by yourself.

 

Every time there is a prompt, similar to Windows C:/>, just start at the beginning of the cycle.

 

Unregister processing:

When _ putch is used to extract the escape character to the screen, the optical mark will return a character, but it will not divide the original character. Therefore, this method is used:

_ Putch (vos_backspace_char );
_ Putch (vos_space_char );
_ Putch (vos_backspace_char );

 

I don't know which hacker came up with it... Haha

 

Just accept a complete command and just pull the carriage return.

 

After the command line is completed, the proxy will be sent. You can take an exam.
