Top Forums UNIX for Advanced & Expert Users how to set the environment variable at run time Post 302068608 by buffoonix on Sunday 19th of March 2006 04:38:16 PM

I'm not sure what your intention is.
Your program can only set the environment for itself and any children it would fork.
It can however not set the environment of its own parent.
Since you mentioned the getenv() and setenv() syscalls I assume you are referring to some C code.
On the other hand different languages use different accessors to the process'es environment.
While C shell compatible interpreters also use the setenv built-in
Bourne shell compatibles use the export built-in to mark an environment variable
(Bash additionally offers the declare -x).
Perl on the other hand uses the global hash %ENV in a package's symbol table.
