Note that in some IDEs, e.g. RStudio or R.app on macOS, the IDE itself opens files from other threads, in addition to the files opened from the main R thread.
Usage
ps_open_files(p = ps_handle())
Value
Data frame with columns: fd
and path
. fd
is numeric
file descriptor on POSIX systems, NA
on Windows. path
is an
absolute path to the file.
