Types ¶
type Process ¶
type Process interface {
// Pid is the process ID for this process.
Pid() uint
// Command name running this process. This is not a path to the
// executable.
Command() string
RunTime() uint64
UserName() string
}
Process is the generic interface that is implemented on every platform and provides common operations for processes.
func FindProcess ¶
FindProcess looks up a single process by pid.
Process will be nil and error will be nil if a matching process is not found.
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) Command ¶
func (p *UnixProcess) Command() string
func (*UnixProcess) Pid ¶
func (p *UnixProcess) Pid() uint
func (*UnixProcess) Refresh ¶
func (p *UnixProcess) Refresh() error
