R: Environment variables of a process

ps_environ {ps} | R Documentation

## Environment variables of a process

### Description

`ps_environ()` returns the environment variables of the process, in a named vector, similarly to the return value of `Sys.getenv()` (without arguments).

### Usage

    ps_environ(p = ps_handle())

    ps_environ_raw(p = ps_handle())

### Arguments

`p` | Process handle.

### Details

Note: this usually does not reflect changes made after the process started.

`ps_environ_raw()` is similar to `p$environ()` but returns the unparsed `"var=value"` strings. This is faster, and sometimes good enough.

These functions throw a `zombie_process` error for zombie processes.

### Value

`ps_environ()` returns a named character vector (that has a `Dlist` class, so it is printed nicely), `ps_environ_raw()` returns a character vector.

### Examples

    p <- ps_handle()
    p
    env <- ps_environ(p)
    env[["R_HOME"]]
