Functions

func New

func New(vfsObj *vfs.VirtualFilesystem, target *kernel.Task, mask linux.SignalSet, flags uint32) (*vfs.FileDescription, error)

New creates a new signal fd.

Types

type SignalFileDescription

type SignalFileDescription struct {
	vfs.FileDescriptionDefaultImpl
	vfs.DentryMetadataFileDescriptionImpl
	vfs.NoLockFD
	vfs.NoAsyncEventFD
	// contains filtered or unexported fields
}

SignalFileDescription implements vfs.FileDescriptionImpl for signal fds.
