syscall
syscall包包含一个指向底层操作系统原语的接口。详细信息取决于基础系统，默认情况下，godoc将显示当前系统的syscall文档。如果要godoc显示其他系统的syscall文档，请将
GOARCH设置为所需的系统。例如，如果要在linux / amd64上查看freebsd / arm的文档，请将
GOARCH设置为arm。 syscall的主要用途是在其他可以为系统提供更轻便接口的软件包中，例如“ os”，“ time”和“ net”。如果可以，请使用这些软件包，而不要使用此软件包。有关此软件包中功能和数据类型的详细信息，请参阅相应操作系统的手册。这些调用返回err == nil表示成功；否则err是描述故障的操作系统错误。在大多数系统上，该错误的类型为syscall.Errno。
注意：此包装已锁定。应该迁移标准Go存储库之外的代码，以使用golang.org/x/sys存储库中的相应软件包。这也是应该应用新系统或版本所需的更新的地方。有关更多信息，请参见https://github.com/golang/go/blob/master/s/go1.4-syscall。
