Interface syscallErrorType

An Errno is an unsigned number describing an error condition. It implements the error interface. The zero Errno is by convention a non-error, so code to convert from Errno to error should use:

  err = nil
if errno != 0 {
err = errno
}

Errno values can be tested against error values using [errors.Is]. For example:

  _, _, err := syscall.Syscall(...)
if errors.Is(err, fs.ErrNotExist) ...
