ENV(2)ENV(2)NAMEenv - environment module
SYNOPSIS
include "env.m";
env = load Env Env->PATH;
getenv: fn(var: string): string;
setenv: fn(var: string, val: string): int;
getall: fn(): list of (string, string);
clone: fn(): int;
new: fn(): int;
DESCRIPTION
Env provides an interface to manipulate environment variables which may
then be shared between processes. Getenv returns the value of the
environment variable var passed as a parameter, or nil if the variable
is not set. It does this by reading the contents of /env/var. Setenv
sets the value of the environment variable var to val. The value may
be nil to unset the variable. It does this by writing the string val to
/env/var. The routine returns a negative number if it fails to set the
variable for any reason. Getall returns all the variables in the cur‐
rent environment as a list of (variable, value) pairs. Clone copies
the current environment and places the process in a new environment
group. Changes now made to the environment will not affect the environ‐
ment of other processes. New places the process in a new empty envi‐
ronment group. Changes made in this new environment will not affect
other processes.
