Functions

func Kill

func Kill(pid int) error

Kill finds a process from a PID and terminates it.

Types

type Process

type Process interface {
	// Pid is the process ID for this process.
	Pid() int

	// PPid is the parent process ID for this process.
	PPid() int

	// Executable name running this process. This is not a path to the
	// executable.
	Executable() string

	// Owner is the account name of the process owner.
	Owner() string

	// Architecture is the architecture of the process.
	Architecture() string
}

Process is the generic interface that is implemented on every platform and provides common operations for processes.

func FindProcess

func FindProcess(pid int) (Process, error)

FindProcess looks up a single process by pid.

Process will be nil and error will be nil if a matching process is not found.

func Processes

func Processes() ([]Process, error)

Processes returns all processes.

This of course will be a point-in-time snapshot of when this method was called. Some operating systems don't provide snapshot capability of the process table, in which case the process table returned might contain ephemeral entities that happened to be running when this was called.

type UnixProcess

type UnixProcess struct {
	// contains filtered or unexported fields
}

UnixProcess is an implementation of Process that contains Unix-specific fields and information.

func (*UnixProcess) Architecture

func (p *UnixProcess) Architecture() string

func (*UnixProcess) CmdLine

func (p *UnixProcess) CmdLine() []string

func (*UnixProcess) Executable

func (p *UnixProcess) Executable() string

Executable returns the process name

func (*UnixProcess) Owner

func (p *UnixProcess) Owner() string

Owner returns the username the process belongs to

func (*UnixProcess) PPid

func (p *UnixProcess) PPid() int

PPid returns the parent process identifier

func (*UnixProcess) Pid

func (p *UnixProcess) Pid() int

Pid returns the process identifier

func (*UnixProcess) Refresh

func (p *UnixProcess) Refresh() error

Refresh reloads all the data associated with this process.
