gettextsettings

Syntax

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

Description

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.

Return Value

None.
