NAME
gl_printf - write formatted output in graphic mode
SYNOPSIS
#include <vgagl.h> 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 neg- ative, the text printing continues at the last position. The special characters , , , a, 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. A good default initialization sequence is: gl_setfont(8, 8, gl_font8x8); gl_setwritemode(FONT_COMPRESSED + WRITEMODE_OVERWRITE); gl_setfontcolors(0, vga_white());
RETURN VALUE
The number of characters printed.
