var ErrNotFound = errors.New("process not found")

ErrNotFound is an error returned by Find*() family, if no target process is found.

Functions ¶

func FindAll ¶

func FindAll(m Matcher) ([]*process.Process, error)

FindAll returns a list of all process.Process instances which are matched with the given mathcer. If process it not found, this returns ErrNotFound.

func FindUnique ¶

func FindUnique(m Matcher) (*process.Process, error)

FindUnique returns a process.Process instance which is matched with the given matcher. If not found, or multiple processes satisfy the matcher, this returns an error. Specifically, on not found case, ErrNotFound is returned.

func WaitForTerminated ¶

func WaitForTerminated(ctx context.Context, p *process.Process, timeout time.Duration) error

WaitForTerminated waits for the process p to be terminated.

Types ¶

type Matcher ¶

type Matcher func(p *process.Process) bool

Matcher is the interface to be passed to Find*() family, representing a condition to identify the target process.

func And ¶

func And(ms ...Matcher) Matcher

And is a utility to compose matchers into one matcher, which is satisfied only when all given matchers are satisfied. If nothing is passed, the returned matcher will match with any process.

func ByExe ¶

func ByExe(exePath string) Matcher

ByExe returns a Matcher which will be satisfied if a process's Exe is the same with the given path. exePath should be always absolute path.
