You are trying to store 242 bytes of information into a single byte. 
This is obviously impossible.  Here is a working version:

#include <conio.h>
#include <stdio.h>

int main(void)
{
    int test = 3;
    char destination[242];  /* window is 11 rows * 11 cols *
                            (1 char for contents + 1 for attributes) */

    /* capture screen character */
    test = gettext(10, 10, 20, 20, &destination);

    printf("gettext test = %d.\n", test);
    printf("press any key to continue...\n");
    getch();
    clrscr();
    getch();

    /* putting back screen character */
    test = puttext(10, 10, 20, 20, &destination);
    printf("puttext test = %d.\n", test);
    return 0;
}






/* vi: set cindent ts=4 sw=4 et tw=72: */
