Overview

Package cabi contains a single WebAssembly function exported as cabi_realloc.

To use, import this package with _:

import _ "go.bytecodealliance.org/x/cabi"

Function realloc is a WebAssembly core function that is validated to have the following core function type:

(func (param $originalPtr i32)
      (param $originalSize i32)
      (param $alignment i32)
      (param $newSize i32)
      (result i32))

The Canonical ABI will use realloc both to allocate (passing 0 for the first two parameters) and reallocate. If the Canonical ABI needs realloc, validation requires this option to be present (there is no default).
