谁能解释一下 Go 标准库中 syscall 包中的以下代码？

// /usr/local/Cellar/go/1.10/libexec/src/syscall/syscall.go
//
//
// Getpagesize and Exit are provided by the runtime    
func Getpagesize() int
func Exit(code int)

没有函数体，也不是接口(interface)。之后怎么样了？

The Go Programming Language Specification

Function declarations

A function declaration may omit the body. Such a declaration provides the signature for a function implemented outside Go, such as an assembly routine.
