## Ports {#ports}

### Darwin {#darwin}

<!-- go.dev/issue/64207 -->
As [announced](go1.22#darwin) in the Go 1.22 release notes,
Go 1.23 requires macOS 11 Big Sur or later;
support for previous versions has been discontinued.

### Wasm {#wasm}

<!-- go.dev/issue/63718 -->
The `go_wasip1_wasm_exec` script in `GOROOT/misc/wasm` has dropped support

			required:  []string{"A", "B", "C"},
			exception: []string{"B"},
			ok:        true,
			out:       "",
		},

		// Test that a feature required on a subset of ports is implicitly satisfied
		// by the same feature being implemented on all ports. That is, it shouldn't
		// say "pkg syscall (darwin-amd64), type RawSockaddrInet6 struct" is missing.

<h3 id="Exported_identifiers">Exported identifiers</h3>

<p>
An identifier may be <i>exported</i> to permit access to it from another package.
An identifier is exported if both:
</p>
<ol>
	<li>the first character of the identifier's name is a Unicode upper case
	letter (Unicode class "Lu"); and</li>

of memory. Because C.malloc cannot fail, it has no two-result form
that returns errno.

# C references to Go

Go functions can be exported for use by C code in the following way:

	//export MyFunction
	func MyFunction(arg1, arg2 int, arg3 string) int64 {...}

	//export MyFunction2
	func MyFunction2(arg1, arg2 int, arg3 string) (int64, *C.char) {...}

They will be available in the C code as:
