Constructors

EmscriptenStack

constructor(exports: EmscriptenStackExports, rootLogger: Logger)

Properties

emscriptenStackBase

val emscriptenStackBase: WasmPtr<<Error class: unknown class>>

Returns the starting address of the stack. This is the address that the stack pointer would point to when no bytes are in use on the stack.

emscriptenStackCurrent

val emscriptenStackCurrent: WasmPtr<<Error class: unknown class>>

Returns the current stack pointer.

emscriptenStackEnd

val emscriptenStackEnd: WasmPtr<<Error class: unknown class>>

Returns the end address of the stack. This is the address that the stack pointer would point to when the whole stack is in use. (The address pointed to by the end is not part of the stack itself). Note that the stack grows down so the address returned by emscriptenStackEnd is smaller than emscriptenStackBase.

emscriptenStackFree

val emscriptenStackFree: Int

Returns the number of free bytes left on the stack. This is required to be fast so that it can be called frequently.

Functions

checkStackCookie

fun checkStackCookie(memory: ReadOnlyMemory)

emscriptenStackRestore

fun emscriptenStackRestore(addr: WasmPtr<Unit>)

Sets the current stack pointer to addr.

emscriptenStackSetLimits

fun emscriptenStackSetLimits(base: WasmPtr<Unit>, end: WasmPtr<Unit>)

Sets the internal values reported by emscriptenStackBase and emscriptenStackEnd. This should only be used by low level libraries such as asyncify fibers.

setStackLimits

fun setStackLimits()

stackCheckInit

fun stackCheckInit(memory: Memory)

Startup routine to initialize the stack.

writeStackCookie

fun writeStackCookie(memory: Memory)
