List processes
`ps()`	Process table
`ps_apps()`	List currently running applications
`ps_pids()`	Ids of all processes on the system
Process query API

`ps_descent()`	Query the ancestry of a process
`ps_environ()` `ps_environ_raw()`	Environment variables of a process
`ps_exe()`	Full path of the executable of a process
`ps_handle()` `as.character(<ps_handle>)` `format(<ps_handle>)` `print(<ps_handle>)`	Create a process handle
`ps_is_running()`	Checks whether a process is running
`ps_memory_info()` `ps_memory_full_info()`	Memory usage information
`ps_name()`	Process name

`ps_ppid()` `ps_parent()`	Parent pid or parent process of a process
`ps_shared_libs()`	List the dynamically loaded libraries of a process
`ps_status()`	Current process status
`ps_terminal()`	Terminal device of the process
`ps_uids()` `ps_gids()`	User ids and group ids of the process
`ps_username()`	Owner of the process
Files and Network Connections
`ps_connections()`	List network connections of a process
`ps_num_fds()`	Number of open file descriptors
`ps_open_files()`	Open files of a process
Process manipulation
`ps_interrupt()`	Interrupt a process
`ps_kill()`	Kill one or more processes
`ps_resume()`	Resume (continue) a stopped process
`ps_send_signal()`	Send signal to a process
`ps_suspend()`	Suspend (stop) the process
`ps_terminate()`	Terminate a Unix process
`ps_get_cpu_affinity()` `ps_set_cpu_affinity()`	Query or set CPU affinity
`ps_windows_nice_values()` `ps_get_nice()` `ps_set_nice()`	Get or set the priority of a process
`ps_wait()`	Wait for one or more processes to terminate, with a timeout
Users
`ps_users()`	List users connected to the system
Disks and files
`ps_disk_partitions()`	List all mounted partitions
`ps_disk_usage()`	Disk usage statistics, per partition
`ps_disk_io_counters()`	System-wide disk I/O counters
`ps_fs_info()`	File system information for files
`ps_fs_mount_point()`	Find the mount point of a file or directory
`ps_fs_stat()`	File status
Other system information
`ps_boot_time()`	Boot time of the system
`ps_os_type()` `ps_is_supported()`	Query the type of the OS
`ps_cpu_count()`	Number of logical or physical CPUs

`ps_system_swap()`	System swap memory statistics
Process tree cleanup
`ps_mark_tree()` `with_process_cleanup()` `ps_find_tree()` `ps_kill_tree()`	Mark a process and its (future) child tree
`CleanupReporter()`	testthat reporter that checks if child processes are cleaned up in tests
