I've read all kinds of tutorials about graphics and stuff, but they allways explain pixel plotting directly to screen ram only, and then they start using double buffered systems with dosmemput etc. functions. So, I ask you: "How can I plot a pixel to a double buffer and then copy it to screen using inline asm?" (two separate functions) My double buffer is a char pointer, (BTW should I use unsigned char?) and the graphics mode is 13h. Thanks for all the possible answers. --Henri Ossi
