cat a /proc entry

[ratheesh kannoth]

Hi,

is there size limit on the buffer content as i am using "cat" command
( so ,not allocating any buffer in userspace, so not doing any
copy_to_user from kernel; simply doing sprintf(buffer, %s , data )
from kernel for a big data )

Hello,

I'm not sure to understand your problem.
Do you write userland or kernelland code?
If you write kernel code, why don't you just use the API behind the
/proc file system?
If you write userland code, what is your problem with the buffer
allocation? You can allocate a buffer as big as your memroy allows it.
