Linux architecture types.

Types

type AuditArch

type AuditArch uint32

func (AuditArch) String

func (a AuditArch) String() string

type Info

type Info struct {
	Name           string         // Linux architecture name (not necessarily the GOARCH name).
	ID             AuditArch      // Linux audit architecture constant.
	SyscallNames   map[string]int // Mapping of syscall names to numbers.
	SyscallNumbers map[int]string // Mapping of syscall numbers to names.
	SeccompMask    int            // A mask to apply to syscall numbers in BPF instructions (e.g. X32_SYSCALL_BIT).
}

Info contains Linux architecture information (name, audit arch, and syscall tables).

func GetInfo

func GetInfo(name string) (*Info, error)

GetInfo returns the arch Info associated with the given architecture name. If an architecture is not fully implemented it will return an error.
