Re: When copy, which function the operation system calls

["Ai Chengshi" <rosemaryai@vip.sina.com>]

Dear James Simmons,

I have read the Linux framebuffer drivers-HOWTO written by you on the web. I
found that the drivers you mentioned were most developed on Linux V2.6.
However, the kernel I used was V2.4. Then how should I do?

Thanks for your help.

Yours sincerely,
Ai Chengshi
