gl_write(3)							Svgalib User Manual						       gl_write(3)

NAME
gl_write, gl_writen - write a text string SYNOPSIS
#include <vgagl.h> void gl_write(int x, int y, char *s); void gl_writen(int x, int y, int n ,char *s); DESCRIPTION
gl_write writes the zero terminated string s to position (x, y) using the currently selected font. gl_writen works similarly, but writes exactly n characters, thus allowing to use the character 0. The kind of text draw operation is set with gl_setwritemode(3). BEWARE! Prior to the of use of gl_write(3) and gl_writen(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()); SEE ALSO

NAME
restoretextmode - save or restore the SVGA registers for textmode. SYNOPSIS
restoretextmode {-r|-w} filename DESCRIPTION
The state of the SVGA is written to or restored from filename using the vga_gettextmoderegs(3) and vga_settextmoderegs(3) functions. As of this writing this file is 385 bytes long but this might change with future versions. Please do not fiddle with the contents of the file except when you know what you do. It might even result in hardware damage. Because of that, you should think twice to make this command available to all users on your system. The purpose of this program is usually to recover from a crashed console due to an svgalib, Xfree or other program bug. First save the state of the SVGA card when on a text console. After the crash restore this state. The savetextmode(1) and textmode(1) script makes this procedure very easy. OPTIONS
-w filename write the SVGA state to the file filename. -r filename restore the SVGA state from the file filename. SEE ALSO
