Method LookupWithFlags

map.go:851–862

LookupWithFlags retrieves a value from a Map with flags. Passing LookupLock flag will look up the value of a spin-locked map without returning the lock. This must be specified if the elements contain a spinlock. Calls Close() on valueOut if it is of type **Map or **Program, and *valueOut is not ni

(key, valueOut any, flags MapLookupFlags)

// Returns an error if the key doesn't exist, see ErrKeyNotExist.

	valueBytes := makeMapSyscallOutput(valueOut, m.fullValueSize)
	if err := m.lookup(key, valueBytes.Pointer(), flags); err != nil {
		return err

	return m.unmarshalValue(valueOut, valueBytes)
