When copy, which function the operation system calls

Hi,

When I typed cp test.bin /dev/fbdir/0, which function does the Linux call? And if I want to write the content in the buffer to LCD controller GRAM, where should I add this function?

Yours Sincerely,

Hi,

When I typed cp test.bin /dev/fbdir/0, which function does the Linux call? 

fb_write in fbmem.c.

And if I want to write the content in the buffer to LCD controller GRAM, 
where should I add this function?

Which kernel, v2.4 or v2.6? The api is different in each case.

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
