Constants ¶

const Host = Linux

Host specifies the host ABI.

Types ¶

type ABI ¶

type ABI interface {
}

ABI is an interface that defines OS-specific interactions.

type FlagSet ¶

type FlagSet []struct {
	Flag uint64
	Name string
}

A FlagSet is a slice of bit-flags and their name.

func (FlagSet) Parse ¶

func (s FlagSet) Parse(val uint64) string

Parse returns a pretty version of val, using the flag names for known flags. Unknown flags remain numeric.

type OS ¶

type OS int

OS describes the target operating system for an ABI.

Note that OS is architecture-independent. The details of the OS ABI will vary between architectures.

const (
	// Linux is the Linux ABI.
	Linux OS = iota
)

func (OS) String ¶

func (o OS) String() string

String implements fmt.Stringer.

type ValueSet ¶

type ValueSet map[uint64]string

ValueSet is a map of syscall values to their name. Parse will use the name or the value if unknown.

func (ValueSet) Parse ¶

func (s ValueSet) Parse(val uint64) string

Parse returns the name of the value associated with `val`. Unknown values are converted to hex.

func (ValueSet) ParseDecimal ¶

func (s ValueSet) ParseDecimal(val uint64) string

ParseDecimal returns the name of the value associated with `val`. Unknown values are converted to decimal.

func (ValueSet) ParseName ¶

func (s ValueSet) ParseName(name string) (uint64, bool)

ParseName returns the flag value associated with 'name'. Returns false if no value is found.
