<code>T</code> is a floating-point type and <code>x</code> can be rounded to <code>T</code>'s

negative zero further simplified to an unsigned zero. Note that constant values never result
in an IEEE negative zero, NaN, or infinity.

C's union types are represented as a Go byte array with the same length.

Go structs cannot embed fields with C types.

Go code cannot refer to zero-sized fields that occur at the end of
non-empty C structs. To get the address of such a field (which is the
only operation you can do with a zero-sized field) you must take the
address of the struct and add the size of the struct.

Cgo translates C types into equivalent unexported Go types.

// iota is a predeclared identifier representing the untyped integer ordinal
// number of the current const specification in a (usually parenthesized)
// const declaration. It is zero-indexed.
const iota = 0 // Untyped int.

// nil is a predeclared identifier representing the zero value for a
// pointer, channel, func, interface, map, or slice type.
var nil Type // Type must be a pointer, channel, func, interface, map, or slice type

	"unicode/utf8"

// A Buffer is a variable-sized buffer of bytes with [Buffer.Read] and [Buffer.Write] methods.
