Constants ¶

const PR_GET_CHILD_SUBREAPER = 37

Return the "child subreaper" setting of the caller, in the location pointed to by (int *) arg2.

const PR_SET_CHILD_SUBREAPER = 36

If arg2 is nonzero, set the "child subreaper" attribute of the calling process; if arg2 is zero, unset the attribute. When a process is marked as a child subreaper, all of the children that it creates, and their descendants, will be marked as having a subreaper. In effect, a subreaper fulfills the role of init(1) for its descendant processes. Upon termination of a process that is orphaned (i.e., its immediate parent has already terminated) and marked as having a subreaper, the nearest still living ancestor subreaper will receive a SIGCHLD signal and be able to wait(2) on the process to discover its termination status.

Functions ¶

func GetOpenFds ¶

func GetOpenFds(pid int) (int, error)

GetOpenFds returns the number of open fds for the process provided by pid

func GetSubreaper ¶

func GetSubreaper() (int, error)

GetSubreaper returns the subreaper setting for the calling process

func SetSubreaper ¶

func SetSubreaper(i int) error

SetSubreaper sets the value i as the subreaper setting for the calling process

Types ¶

type Exit ¶

type Exit struct {
	Pid    int
	Status int
}

Exit is the wait4 information from an exited process

func Reap ¶

func Reap() (exits []Exit, err error)

Reap reaps all child processes for the calling process and returns their exit information
