Prototype

void gettextinfo(struct text_info *r);

Description

Gets text mode video information.

gettextinfo fills in the text_info structure pointed to by r with the current text video information.

The text_info structure is defined in conio.h as follows:

struct text_info {

unsigned char winleft; /* left window coordinate */

unsigned char wintop; /* top window coordinate */

unsigned char winright; /* right window coordinate */

unsigned char winbottom; /* bottom window coordinate */

unsigned char attribute; /* text attribute */

unsigned char normattr; /* normal attribute */

unsigned char currmode; /* BW40, BW80, C40, C80, or C4350 */

unsigned char screenheight; /* text screen's height */

unsigned char screenwidth; /* text screen's width */

unsigned char curx; /* x-coordinate in current window */

unsigned char cury; /* y-coordinate in current window */

};

Remarque :  Do not use this function in Win32 GUI applications.

Return Value

None. Results are returned in the structure pointed to by r.

Example

 #include <conio.h>
 int main(void)
  {
    struct text_info ti;
    gettextinfo(&ti);
    cprintf("window left      %2d\r\n",ti.winleft);
    cprintf("window top       %2d\r\n",ti.wintop);
    cprintf("window right     %2d\r\n",ti.winright);
    cprintf("window bottom    %2d\r\n",ti.winbottom);
    cprintf("attribute        %2d\r\n",ti.attribute);
    cprintf("normal attribute %2d\r\n",ti.normattr);
    cprintf("current mode     %2d\r\n",ti.currmode);
    cprintf("screen height    %2d\r\n",ti.screenheight);
    cprintf("screen width     %2d\r\n",ti.screenwidth);
    cprintf("current x        %2d\r\n",ti.curx);
    cprintf("current y        %2d\r\n",ti.cury);
    return 0;
 }
