| Summary : Read Environment Variables of any Process
|
Description :
Proc::Info::Environment retrieves the settings of environment variables in
arbitrary running processes of the operating system.
For example,
use Proc::Info::Environment;
my $proc_env = Proc::Info::Environment->new();
my $env = $proc_env->env( 123 );
will retrieve the environment settings of the process with the pid 123 and
(if this process exists and is readable by the user) return them as a hash
reference in $env.
As an illustrative (but not very useful) example, retrieving
my $env = $proc_env->env( $$ );
will return a reference to a hash similar to \'%ENV\', which contains the
environment variables of the current process.
Reading other processes\' environment variables is only possible if the
operating system (a) supports a method to do this and (b) the user of the
currently running process is either root, or has the same uid as the
process whose variables it wants to read.
Proc::Info::Environment is currently supported only for specific Unix
systems. On Linux, it will use the procfs file system mounted under /proc
to get the information needed. It will read the file /proc/xxx/environ,
where xxx is the pid of the target process.
To verify if Proc::Info::Environment supports your operating system, run
Proc::Info::Environment::os_supported(), which returns a true value if it
is supported. If the OS is unsupported, the new() constructor will die()
with an error message listing all currently supported operating systems.
The module\'s architecture allows for easy support of other systems, if you
want support for one and know how the information is provided, drop me an
email.
