 +==== Description of gettextsettings ==== 
 +<code c>
 +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.
