Environment variables of a process
ps_environ() returns the environment variables of the process, in a
named vector, similarly to the return value of Sys.getenv()
(without arguments).
ps_environ(p = ps_handle()) ps_environ_raw(p = ps_handle())
p |
Process handle. |
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.
ps_environ() returns a named character vector (that has a
Dlist class, so it is printed nicely), ps_environ_raw() returns a
character vector.
