Refs: https://github.com/nodejs/uvwasi/pull/185 Add stub for sock_accept so that we have stubs for all of the sock methods in wasi_snapshot_preview1. Its a bit awkward as the method was added after the initial definitial of wasi_snapshot-preview1 but I think it should be semver minor at most to add the method. Depends on https://github.com/nodejs/uvwasi/pull/185 being landed in uvwasi first and an updated version of uvwasi that includes that being pulled into Node.js Signed-off-by: Michael Dawson <mdawson@devrus.com> PR-URL: https://github.com/nodejs/node/pull/46434 Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Colin Ihrig <cjihrig@gmail.com>
