/dev/null implementation question

/dev/null implementation question

[Michael Nitschinger]

Hello,

I asked myself how /dev/null is implemented in C, but i didn't find anything in the documentation or generally on the internet. It would be great if someone could tell me where i can find the source for this device or how it is implemented, because it's really hard for me to crawl through the whole sourcetree.

thanks in advance, kind regards
Michael Nitschinger

(p.s.: it would be great if you can Cc me in your answers because i am not subscribed to the mailinglist! thanks)

See linux/drivers/char/mem.c, look for null_fops.
