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);
DESCRIPTIONgl_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 allow‐
ing 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());
