Constants

const Compiler = "tinygo"

const GOARCH = "amd64"

const GOOS = "linux"

const TargetBits = 64

The bitness of the CPU (e.g. 8, 32, 64).

Functions

func Caller

func Caller(skip int) (pc uintptr, file string, line int, ok bool)

func Callers

func Callers(skip int, pc []uintptr) int

func GOMAXPROCS

func GOMAXPROCS(n int) int

func GOROOT

func GOROOT() string

func Goexit

func Goexit()

Goexit terminates the currently running goroutine. No other goroutines are affected.

Unlike the main Go implementation, no deffered calls will be run.

func Gosched

func Gosched()

func LockOSThread

func LockOSThread()

LockOSThread wires the calling goroutine to its current operating system thread. Stub for now Called by go1.18 standard library on windows, see https://github.com/golang/go/issues/49320

func NumCPU

func NumCPU() int

NumCPU returns the number of logical CPUs usable by the current process.

The set of available CPUs is checked by querying the operating system at process startup. Changes to operating system CPU allocation after process startup are not reflected.

func NumCgoCall

func NumCgoCall() int

Stub for NumCgoCall, does not return the real value

func NumGoroutine

func NumGoroutine() int

Stub for NumGoroutine, does not return the real value

func Stack

func Stack(buf []byte, all bool) int

func UnlockOSThread

func UnlockOSThread()

UnlockOSThread undoes an earlier call to LockOSThread. Stub for now

func Version

func Version() string

Version returns the Tinygo tree's version string. It is the same as goenv.Version, or in case of a development build, it will be the concatenation of goenv.Version and the git commit hash.

Types

type Cond

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

Cond is a simplified condition variable, useful for notifying goroutines of interrupts.

func (*Cond) Notify

func (c *Cond) Notify() bool

Notify sends a notification. If the condition variable already has a pending notification, this returns false.

func (*Cond) Poll

func (c *Cond) Poll() bool

Poll checks for a notification. If a notification is found, it is cleared and this returns true.

func (*Cond) Wait

func (c *Cond) Wait()

Wait for a notification. If the condition variable was previously notified, this returns immediately.

type Error

type Error interface {
	error

	RuntimeError()
}

The Error interface identifies a run time error.

type Frame

type Frame struct {
	Function string

	File string
	Line int
	PC   uintptr
}

type Frames

type Frames struct {
}

func CallersFrames

func CallersFrames(callers []uintptr) *Frames

func (*Frames) Next

func (ci *Frames) Next() (frame Frame, more bool)

type Func

type Func struct {
}

func FuncForPC

func FuncForPC(pc uintptr) *Func

func (*Func) FileLine

func (f *Func) FileLine(pc uintptr) (file string, line int)

func (*Func) Name

func (f *Func) Name() string
