Types

type BpfModuleTables

type BpfModuleTables struct {
	Module       ModuleStub
	Table        *Table
	CPUFreqTable *Table
}

func AttachBPFAssets

func AttachBPFAssets() (*BpfModuleTables, error)

type ModuleStub

type ModuleStub struct{}

type Table

type Table struct {
}

Table references a BPF table.

func (*Table) DeleteAll

func (table *Table) DeleteAll()

func (*Table) Iter

func (table *Table) Iter() *TableIterator

Iter returns an iterator to list all table entries available as raw bytes.

type TableIterator

type TableIterator struct {
	// contains filtered or unexported fields
}

TableIterator contains the current position for iteration over a *bcc.Table and provides methods for iteration.

func (*TableIterator) Key

func (it *TableIterator) Key() []byte

Key returns the current key value of the iterator, if the most recent call to Next returned true. The slice is valid only until the next call to Next.

func (*TableIterator) Leaf

func (it *TableIterator) Leaf() []byte

Leaf returns the current leaf value of the iterator, if the most recent call to Next returned true. The slice is valid only until the next call to Next.

func (*TableIterator) Next

func (it *TableIterator) Next() bool

Next looks up the next element and return true if one is available.
