Re: How to access Linux Kernel environment Variables ?

Thanks Richard for your response.

Is there any system call in Linux which can access and set variables
in /proc/cmdline ? (Similar to kenv() in FreeBSD which can access and
set variables in /boot/loader.conf).

I would like to use that system call in linux C code, the way I am
using kenv() in freeBSD environment.

Regards
Santosh
