Package-Level Type Names (total 3, in which 2 are exported)

	/* sort exporteds by: alphabet | popularity */
	 type GetRandomFlag uintptr (basic type)
		GetRandomFlag is a flag supported by the getrandom system call.

		As Inputs Of (at least one exported)
			func GetRandom(p []byte, flags GetRandomFlag) (n int, err error)
		As Types Of (total 2, both are exported)
			const GRND_NONBLOCK
			const GRND_RANDOM

	 type SiginfoChild (struct)
		SiginfoChild is a struct filled in by Linux waitid syscall.
		In C, siginfo_t contains a union with multiple members;
		this struct corresponds to one used when Signo is SIGCHLD.
		
		NOTE fields are exported to be used by TestSiginfoChildLayout.

		Fields (total 7, in which 6 are exported)
			Pid int32
			siErrnoCode.Code int32
			siErrnoCode.Errno int32
			Signo int32
			Status int32
			Uid uint32
			/* one unexported ... *//* one unexported: */
			siErrnoCode siErrnoCode
				// Two int32 fields, swapped on MIPS.

		Methods (only one, which is exported)
			(*SiginfoChild) WaitStatus() (ws syscall.WaitStatus)
				WaitStatus converts SiginfoChild, as filled in by the waitid syscall,
				to syscall.WaitStatus.

		As Inputs Of (at least one exported)
			func Waitid(idType int, id int, info *SiginfoChild, options int, rusage *syscall.Rusage) error

	/* one unexported ... *//* one unexported: */
	 type siErrnoCode (struct)

		Fields (total 2, both are exported)
			Code int32
			Errno int32

	const AT_FDCWD = -100
	const AT_REMOVEDIR = 512
	const AT_SYMLINK_NOFOLLOW = 256
	const GRND_NONBLOCK GetRandomFlag = 1
		GRND_NONBLOCK means return EAGAIN rather than blocking.

	const GRND_RANDOM GetRandomFlag = 2
		GRND_RANDOM means use the /dev/random pool instead of /dev/urandom.

	const NoFollowErrno syscall.Errno = 40
		NoFollowErrno is the error returned from open/openat called with
		O_NOFOLLOW flag, when the trailing component (basename) of the path
		is a symbolic link.
