Hi all,
Is there any system call in Linux which serve the purpose of "kenv()"
of FreeBSD ?
In FreeBSD:
-----------------
Kernel environment variables are saved at "/boot/loader.conf" and
those variables can be accessed using "kenv()" system call in C
program.
----------------
Is there any similar functionality available in Linux kernel ?
Thanks
Santosh

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

Create a wrapper function which behaves like kenv().
Should be doable in a few lines of code.
Thanks,
