gl_write, gl_writen - write a text string
#include <vgagl.h> void gl_write(int x, int y, char *s); void gl_writen(int x, int y, int n ,char *s);
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());
