Functions ¶
func CreateUnixSocket ¶
CreateUnixSocket creates a unix socket and returns the listener
func EpollCreate1 ¶
EpollCreate1 directly calls unix.EpollCreate1
func ForceRemoveAll ¶
ForceRemoveAll on unix is just a wrapper for os.RemoveAll
func GetLocalListener ¶
GetLocalListener returns a listerner out of a unix socket.
func GetOpenFds ¶
GetOpenFds returns the number of open fds for the process provided by pid
func GetSubreaper ¶ added in v1.2.0
GetSubreaper returns the subreaper setting for the calling process
func GetSystemCPUUsage ¶
GetSystemCPUUsage returns the host system's cpu usage in nanoseconds. An error is returned if the format of the underlying file does not match.
Uses /proc/stat defined by POSIX. Looks for the cpu statistics line and then sums up the first seven fields provided. See `man 5 proc` for details on specific field information.
func RunningPrivileged ¶ added in v1.1.4
func RunningPrivileged() bool
RunningPrivileged returns true if the effective user ID of the calling process is 0
func RunningUnprivileged ¶ added in v1.1.4
func RunningUnprivileged() bool
RunningUnprivileged returns true if the effective user ID of the calling process is not 0
func SetOOMScore ¶
SetOOMScore sets the oom score for the provided pid
func SetSubreaper ¶ added in v1.2.0
SetSubreaper sets the value i as the subreaper setting for the calling process
func StatATimeAsTime ¶
StatATimeAsTime returns st.Atim as a time.Time
