[Fwd: Folow-up question regarding the linux-fb port of gtk]

[Abhishek Chitlangia <abhishek chitlangia jhu edu>]

I'm in the process of porting gtk to a developmental OS that has its own 
basic windowing system that controls all memory and device accesses. 
This means that when I open a new display, the mmap call that maps the 
display's fb_mem pointer to the memory-mapped linux-fb (/dev/fb0) is 
replaces with a call to a function that returns a memory region that is 
to be assumed to be the linux fb. Hence, all operations that change the 
fb contents (like changing pixel contents) will now have to be followed 
up with a call to the windowing system to tell it to blit the contents 
onto the actual fb.

My question is this:
Is there one file or set of files whose functions write directly to the 
linux fb?
gdkrender-fb.c is one: are there any others?

appreciate any help. thanks.
