Reading the Device Status Report ANSI escape sequence reply

Question

I\'m trying to retrieve the coordinates of cursor in a VT100 terminal using the following code:

void getCursor(int* x, int* y) {
  printf(\"\\033[6n\");
   s

#include 
#include 
#include 

void readCoord(void* row, void* col){
    int i = 0;
    char* input = malloc(10);
    printf("\e[6n");
    while(!_kbhit()) _sleep(1);
    while(_kbhit()) *(input + (i++)) = getch();
    *(input + i) = '\0';
    sscanf(input, "\e[%d;%dR", row, col);
}

void main(void){
    int i = 0, r, c;
    char* coord = malloc(10);
    printf("Hello");
    readCoord(&r , &c);
    printf("\nYour coordinate is (%d, %d)", c, r);
}

_kbhit() is used to detect input (DSR are treated as though typed at the keyboard), and getch() to read and remove the character from standard input

This program relies on conio.h, which is not a standard and hence not recommended for portable C programs.
