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 */
 };

Note: 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;
}
