gettextsettings

Syntax of gettextsettings

#include <graphics.h>
void gettextsettings(struct textsettingstype *texttypeinfo);
 

Description of gettextsettings

gettextsettings fills the textsettingstype structure pointed to by
textinfo with information about the current text font, direction, size,
and justification. The textsettingstype structure used by gettextsettings
is defined in graphics.h as follows:
struct textsettingstype {
   int font;
   int direction;
   int charsize;
   int horiz;
   int vert;
};
See settextstyle for a description of these fields.
