int gl_printf(int x, int y, const char *fmt, ...);
DESCRIPTION
gl_printf
writes, like
printf(3)
a formatted string to position
(x, y)
using the currently selected font. If one or both of
x and y
is negative, the text printing continues at the last position. The
special characters
\b, \r,
\n, \a,
\t and \v
have the usual effects.
Printing wraps at the screen borders. Nevertheless, behaviour is undefined
if not a single characters fits on the screen or if the initial position
is outside the screen.
The kind of text draw operation is set with
gl_setwritemode(3).
BEWARE!
Prior to the of use of
gl_printf(3)
you must set a font.
