Control character manipulation

[Guest]

Hello

In a C++ program, I would like to change the string

"ty^Hypescript ^H ^H^H ^H^H ^H^H ^H^H ^H^H ^H^H ^H^
^H^H ^H^H ^H^H ^H^G^G^G^G^Gty^Hypescript ^H ^H^H ^H^H ^H^H ^H^M"

into the string

"typescript"


The letters like '^H', '^H^H', and '^G' represents some of the ANSI control characters such as backspace. (the characters are shown on VI editor.

So, I think it's possible to process control characters within a code, like a VT100 virtual terminal does.( In deed, I am not sure whether the process is done in a terminal, shell or whatever.

If you have a sample code or a function to suggest, please post them. Thank you.

void remove_ctrl_chars(char* dst, const char* src)
while (*src != '\0')
switch(*src)
case '\x07': break
case '\x08': break
case '\x13': break
default
*dst = *src
dst++

src++
