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.
