<p>
For instance, if the deferred function is
a <a href="#Function_literals">function literal</a> and the surrounding
function has <a href="#Function_types">named result parameters</a> that
are in scope within the literal, the deferred function may access and modify
the result parameters before they are returned.

C.sizeof_struct_stat.

A C function may be declared in the Go file with a parameter type of
the special name _GoString_. This function may be called with an
ordinary Go string value. The string length, and a pointer to the
string contents, may be accessed by calling the C functions

	size_t _GoStringLen(_GoString_ s);
	const char *_GoStringPtr(_GoString_ s);

These functions are only available in the preamble, not in other C

The [Func] type, which represents a function or method symbol, now
has a [Func.Signature] method that returns the function's type, which

						wantName = wantName[1:]
					}
					if i := strings.Index(wantName, "+"); i >= 0 {
						wantName = wantName[:i]
					}
				}
				if ok != isFuncSym || name != wantName {
					t.Errorf("fail at %s as function address: got %s, %v; expected %s, %v", test.input, name, ok, wantName, isFuncSym)
				}
			}
		})
	}
}

Each function also needs annotations giving the location of
live pointers in its arguments, results, and local stack frame.
For an assembly function with no pointer results and
either no local stack frame or no function calls,
the only requirement is to define a Go prototype for the function
in a Go source file in the same package. The name of the assembly

// defined by a split function of type [SplitFunc]; the default split
// function breaks the input into lines with line termination stripped. [Scanner.Split]
// functions are defined in this package for scanning a file into
// lines, bytes, UTF-8-encoded runes, and space-delimited words. The
// client may instead provide a custom split function.
//

	// Create a custom split function by wrapping the existing ScanWords function.
	split := func(data []byte, atEOF bool) (advance int, token []byte, err error) {
		advance, token, err = bufio.ScanWords(data, atEOF)
		if err == nil && token != nil {
			_, err = strconv.ParseInt(string(token), 10, 32)
		}
		return
	}
	// Set the split function for the scanning operation.
	scanner.Split(split)

	if symName != funcName {
		t.Fatalf("expected function name %v; got %v", symName, funcName)
	}
	fi1, err := os.Stat("addr2line_test.go")
	if err != nil {
		t.Fatalf("Stat failed: %v", err)
	}
