Thread: Reading a character from the screen

Is there a function I can use to read in a character from the screen? This would be on regular DOS mode. (Not console). Would it be easier to use assembler blocks to read in a character? My ultimate goal is to read in an array of characters into a var[]. This way I can write over current text and then replace it.

Um, I may be misunderstanding your question, but is ths what you want?

Code:

#include <iostream> 
using namespace std;

int main ( void ) 
{ 
  char c;
  cin.get ( c );
  while ( c != '\n' ) {
    cout.put ( c );
    cin.get ( c );
  }
  cout<<endl;
  return EXIT_SUCCESS; 
}

No, I know how to get keyboard input, but I want to be able to (in 80x25 screen) be able to pick a coordinate and then find what text is at that location. Like if I just printed a text file to the screen and I want to find what character is on the screen at location 14,20.

The only way I can think of involves asm.

You would need to loop through the screen buffer while storing every other byte in an array starting with the first character byte. Not too complicated really, but my materials are at home. If you have the resources, try to figure it out...

I think...
