memcpy_tofs... wheres it at?

[Sharath <sharath_75@yahoo.com>]

Hi...

just dwelling into writing a device driver and yes
have got some of it sorted out.. however I would like
to know where the prototype for memcpy_tofs recides.

I'm using 2.4.18 Kernel and don't seem to fine\d it
anywhere.. I have found the #defines which define
copy_to_user(...) as memcpy_tofs but when I include
the libraries, I get problems with the tagged
initialization of the read funtion in file_operations.

thanks in advance
sharath
