ENV(2) ENV(2)
NAME
env - 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 vari-
ables 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 current environment as a list of
(variable, value) pairs. Clone copies the current environ-
ment and places the process in a new environment group.
Changes now made to the environment will not affect the
environment of other processes. New places the process in a
new empty environment group. Changes made in this new envi-
ronment will not affect other processes.
