So here's the tea ☕ this function returns true if all of the following are doing their thing:

• the connection is connected to the NBD server 🔌
• the handshake has completed 🤝

When you're in this state, the handle is ready to issue commands. main character handle energy, honestly 💅 she's ready, she's available, she's about to go issue some commands 💖

But — and I need you to hear me on this — the following parameters must not be NULL: "h". For more info, go peek at "Non-NULL parameters" over in libnbd(3) 📖
