[C400-L] Environment Variable

[Srikanth_D <Srikanth_D@xxxxxxxxxx>]

hi all,

i have a parent process which spawns a child process. child process
basically is a multithreaded socket server. the parent process does a
putenv("SERVERUP = YES"); and sends this to the child (sixth parameter in
spawn).
i would like to know whether the parent can change this environment variable
in the child process, this is required because logic of the child process is
to keep listening uptill the value of SERVERUP is YES. if there is a better
way of shutting down the child i would be glad to learn about it.

thanks in advance.
