The OP didn't seem to be asking about propagating the setting to the
parent process (assuming that "parent process" is meaningful). As far
as I can tell, the POSIX setenv() function (not standard C) would
satisfy the requirement he stated. Whether it would satisfy his
actual requirement is another question.
<OT>In Unix-like systems, there are various ways for a process to set
one of its own environment variables in response to information from a
child process. You demonstrated one of them in part of your article
that I ruthlessly snipped; other ways are possible.
comp.unix.programmer would be a better place to discuss it -- after
checking any FAQ lists, since this kind of question comes up
frequently.</OT>
