| as.character.ps_handle | Create a process handle |
| CleanupReporter | testthat reporter that checks if child processes are cleaned up in tests |
| errno | List of 'errno' error codes |
| format.ps_handle | Create a process handle |
| print.ps_handle | Create a process handle |
| ps | Process table |
| ps_boot_time | Boot time of the system |
| ps_children | List of child processes (process objects) of the process. Note that this typically requires enumerating all processes on the system, so it is a costly operation. |
| ps_cmdline | Command line of the process |
| ps_connections | List network connections of a process |
| ps_cpu_count | Number of logical or physical CPUs |
| ps_cpu_times | CPU times of the process |
| ps_create_time | Start time of a process |
| ps_cwd | Process current working directory as an absolute path. |
| ps_descent | Query the ancestry of a process |
| ps_disk_partitions | List all mounted partitions |
| ps_disk_usage | Disk usage statistics, per partition |
| ps_environ | Environment variables of a process |
| ps_environ_raw | Environment variables of a process |
| ps_exe | Full path of the executable of a process |
| ps_find_tree | Mark a process and its (future) child tree |
| ps_get_nice | Get or set the priority of a process |
| ps_gids | User ids and group ids of the process |
| ps_handle | Create a process handle |
| ps_interrupt | Interrupt a process |
| ps_is_running | Checks whether a process is running |
| ps_is_supported | Query the type of the OS |
| ps_kill | Kill a process |
| ps_kill_tree | Mark a process and its (future) child tree |
| ps_loadavg | Return the average system load over the last 1, 5 and 15 minutes as a tuple. The “load” represents the processes which are in a runnable state, either using the CPU or waiting to use the CPU (e.g. waiting for disk I/O). On Windows this is emulated by using a Windows API that spawns a thread which keeps running in background and updates results every 5 seconds, mimicking the UNIX behavior. Thus, on Windows, the first time this is called and for the next 5 seconds it will return a meaningless (0.0, 0.0, 0.0) vector. The numbers returned only make sense if related to the number of CPU cores installed on the system. So, for instance, a value of 3.14 on a system with 10 logical CPUs means that the system load was 31.4% percent over the last N minutes. |
| ps_mark_tree | Mark a process and its (future) child tree |

| ps_os_type | Query the type of the OS |
| ps_parent | Parent pid or parent process of a process |
| ps_pid | Pid of a process handle |
| ps_pids | Ids of all processes on the system |
