Overview

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.
