Synopsis: Return value for environment name.
Syntax: getenv ( NAME )
Description:
Getenv searches the current environment for a variable with
name NAME. The value of the environment variable is returned
as a string.
Exactly how getenv behaves is depends upon the underlying
operating system implementation. On UNIX system getenv will
return a NULL string if the environment variable does not
exist.
