Types

type Conn

type Conn interface {
	// SyscallConn returns a raw network connection.
	SyscallConn() (RawConn, error)
}

Conn is implemented by some types in the net and os packages to provide access to the underlying file descriptor or handle.

type Errno

type Errno uintptr

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
}
