Functions ¶
func ConvertStat ¶ added in v0.4.0
ConvertStat will convert a *syscall.Stat_t to a *Stat_t. It returns an error if buf is not of type *syscall.Stat_t.
func GetDeviceSize ¶ added in v0.4.0
func GetFileDescriptorLimit ¶ added in v0.3.2
GetFileDescriptorLimit returns the current limit and maximum limit on number of open file descriptors.
func SetMyPriority ¶ added in v0.3.2
SetMyPriority sets the priority of the current process, for all OS threads. On platforms which do not support changing the process priority, an error is always returned.
func SetNetNamespace ¶
SetNetNamespace is a safe wrapper for the Linux setns(fd, CLONE_NEWNET) system call. On Linux it will lock the current goroutine to an OS thread and set the network namespace to the specified file descriptor. On failure or on other platforms an error is returned.
func SetPriority ¶ added in v0.4.0
SetPriority sets the CPU priority of the specified process, for all OS threads. If pid is zero, the priority of the calling process is set. On platforms which do not support changing the process priority, an error is always returned.
func SetSysProcAttrChroot ¶ added in v0.4.0
func SetSysProcAttrChroot(attr *syscall.SysProcAttr, chroot string) error
SetSysProcAttrChroot sets the Chroot field in attr. It returns an error if this operation is not supported.
func UnshareMountNamespace ¶
func UnshareMountNamespace() error
UnshareMountNamespace is a safe wrapper for the Linux unshare(CLONE_NEWNS) system call. On Linux it will lock the current goroutine to an OS thread and unshare the mount namespace (the thread will have a private copy of the previous mount namespace). On failure or on other platforms an error is returned.
func UnshareNetNamespace ¶
UnshareNetNamespace is a safe wrapper for the Linux unshare(CLONE_NEWNET) system call. On Linux it will lock the current goroutine to an OS thread and unshare the network namespace (the thread will have a fresh network namespace). The file descriptor for the new network namespace and the Linux thread ID are returned. On failure or on other platforms an error is returned.
