R: Open files of a process

ps_open_files {ps} | R Documentation

## Open files of a process

### Description

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())

### Arguments

`p` | Process handle.

### Details

For a zombie process it throws a `zombie_process` error.

### Value

Data frame, or tibble if the tibble package is available, with columns: `fd` and `path`. `fd` is numeric file descriptor on POSIX systems, `NA` on Windows. `path` is an absolute path to the file.

    ps_open_files(p)
    close(f)
