Hi Sandip!
Will this actually work from a shell script? Assuming that Manish was
running it in a subshell, i.e.
#!/bin/sh
export a="boo"
Doesn't "export" export a variable to the environment of the shell within
which it's run? Child processes, of course inherit environment variables,
but how would one pass it onto a parent?
Also, even if it does work for the C program, assuming it's running in the
same script, IMHO, it wouldn't work for the PHP script unless he's running
the php binary under the same shell or the first httpd listener thread/process
under the same shell...
In Apache, mod_php, mod_cgid, mod_cgi fix up the environment for you before
they do an execve+fork, which is why you can use them from PHP.
So my bets would be:
part 1- C program - no it won't work, and I don't know how to make it work.
The first term that comes to mind is IPC and my mind jumps out of my skull
and totters away every time I try to think any further.
part 2- PHP script- um... ditto...
