Global change in environment variables from inside C programs
|

| Hi,
How can I make global changes to environment variables in Linux/Unix
from inside C programs? I want this modified value to be available to
independent scripts/processes. I figured, sentenv()/putenv() don't
change the values of the environment variables permanently. So by what
other way can I achieve this? Any suggestion will be highly
appreciated.
Best regards,
Rajarshi
p.s. This is needed for communication between a server and a CGI
script (written in perl) using environment variables.

Read the comp.unix.questions FAQ, which has a long section addressing
this issue. The short answer: there's no general way.
