The C types __int128_t and __uint128_t are represented by [16]byte.

A few special C types which would normally be represented by a pointer
type in Go are instead represented by a uintptr.  See the Special
cases section below.

To access a struct, union, or enum type directly, prefix it with
struct_, union_, or enum_, as in C.struct_stat.

The size of any C type T is available as C.sizeof_T, as in
C.sizeof_struct_stat.

	// as the section reader offset & size were < 0.
	NewReader(bytes.NewReader(data), int64(len(data))+1875)

	// Uname should give a user name.
	Uname() (string, error)
	// Gname should give a group name.
	Gname() (string, error)
}

files are treated as directives for the test's main package.
In any other context, `//go:debug` lines are ignored by the toolchain;
`go` `vet` reports such lines as misplaced.

## GODEBUG History {#history}

This section documents the GODEBUG settings introduced and removed in each major Go release
for compatibility reasons.
Packages or programs may define additional settings for internal debugging purposes;
for example,

//	         if v is nil, len(v) is zero.
//
// For some arguments, such as a string literal or a simple array expression, the
// result can be a constant. See the Go language specification's "Length and
// capacity" section for details.
func len(v Type) int

// The cap built-in function returns the capacity of v, according to its type:
//
//	Array: the number of elements in v (same as len(v)).
