ps_environ: Environment variables of a process

Description Usage Arguments Details Value See Also Examples

View source: R/low-level.R

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

3

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.
