framebuffer implementation

v6sa · 05-10-2005, 04:03 AM

hello! im writing a notepad like program for linux framebuffer, currently i use just mmap-ed /dev/fd0 but problem is that command line cursor blinks still thru, and when program is running and you switch to other terminal, pixels are also being drawn there. i checked out bogl, it work right way, it should support 32bit truecolor mode too, but i couldn't find usable example for 32bits, only 16 colours. what to do?

Hi,

You can put the below code to disable the cursor.

handle = open(FB_TTY, O_RDWR);
write(handle, "\033[?1c", 5);

In this way, you can disable the cursor. I have a doubt . Please help me.

How to display a string or a character onto a frame buffer? This is urgent. Thank you. Please mail me to mouli123@gmail.com

With regards,
Chandramouli
