outtext

Syntax

#include <graphics.h>
void outtext(char *textstring);

Description

outtext displays a text string in the viewport, using the current font, direction, and size.

outtext outputs textstring at the current position (CP). If the horizontal text justification is LEFT_TEXT and the text direction is HORIZ_DIR, the CP's x-coordinate is advanced by textwidth(textstring). Otherwise, the CP remains unchanged.

To maintain code compatibility when using several fonts, use textwidth and textheight to determine the dimensions of the string.

If a string is printed with the default font using outtext, any part of the string that extends outside the current viewport is truncated.

outtext is for use in graphics mode; it will not work in text mode.

Return Value

None.

      getch();
      exit(1);               /* terminate with an error code */
   }

   midx = getmaxx() / 2;

   /* move the CP to the center of the screen */
