GetRandomFlag is a flag supported by the getrandom system call.

// GRND_NONBLOCK means return EAGAIN rather than blocking.

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.
type SiginfoChild struct {
Signo int32
Pid int32
Uid uint32
Status int32
// contains filtered or unexported fields
}
func (s *SiginfoChild) WaitStatus() (ws syscall.WaitStatus)
WaitStatus converts SiginfoChild, as filled in by the waitid syscall, to syscall.WaitStatus.
