package unix
import "github.com/cilium/ebpf/internal/unix"
Package unix re-exports Linux specific parts of golang.org/x/sys/unix.
It avoids breaking compilation on other OS by providing stubs as follows:
- Invoking a function always returns an error.
- Errnos have distinct, non-zero values.
- Constants have distinct but meaningless values.
- Types use the same names for members, but may or may not follow the Linux layout.

type Errno ¶
type Errno uintptr
Errno is a Windows compatibility shim for Unix errnos.
const ( EPERM Errno = 1 ENOENT Errno = 2 ESRCH Errno = 3 EINTR Errno = 4 E2BIG Errno = 7 EBADF Errno = 9 EAGAIN Errno = 11 EACCES Errno = 13 EFAULT Errno = 14 EEXIST Errno = 17 ENODEV Errno = 19 EINVAL Errno = 22 ENFILE Errno = 23 EMFILE Errno = 24 ENOSPC Errno = 28 ENOSYS Errno = 40 ENOTEMPTY Errno = 41 EILSEQ Errno = 42 ENOTSUP Errno = 129 EOPNOTSUPP Errno = 130 ETIMEDOUT Errno = 138 EWOULDBLOCK Errno = 140 )
Windows specific constants for Unix errnos.
The values do not always match Linux, for example EILSEQ and EOPNOTSUPP.
See https://learn.microsoft.com/en-us/cpp/c-runtime-library/errno-constants?view=msvc-170
const ( ENOTSUPP Errno = Errno(syscall.APPLICATION_ERROR) + iota ESTALE )
These constants do not exist on Windows and therefore have a non-zero dummy value.
