Function WrapSyscallConn

internal/credentials/syscallconn.go:49–58

WrapSyscallConn tries to wrap rawConn and newConn into a net.Conn that implements syscall.Conn. rawConn will be used to support syscall, and newConn will be used for read/write. This function returns newConn if rawConn doesn't implement syscall.Conn.

(rawConn, newConn net.Conn)

//
// This function returns newConn if rawConn doesn't implement syscall.Conn.
func WrapSyscallConn(rawConn, newConn net.Conn) net.Conn {
	sysConn, ok := rawConn.(syscall.Conn)
	if !ok {
		return newConn
	}
	return &syscallConn{
		Conn:    newConn,
		sysConn: sysConn,
	}
