STRUCT CMP_CONNECTION(9)

💖 NAME 💖

struct cmp_connection — manages an isochronous connection to a device. That's the whole vibe, bestie. It's the little struct in the Kernel API Manual that keeps an isochronous link to a device from going feral. 💅

✨ SYNOPSIS ✨

       struct cmp_connection {
           int speed;
        };

🎀 Members 🎀

• speed — the connection's actual speed. literally the real one, no cosplay. ⭐

🦋 Description 🦋

okay so this structure manages (using CMP) an isochronous stream between the local computer and a device's input plug (iPCR) and output plug (oPCR). 🎀

There is no corresponding oPCR created on the local computer, so it is not possible to overlay connections on top of this one. like, the local side just doesn't get its own matching oPCR — that's the rule, bestie. 🫶

no cap: because that corresponding oPCR does not exist on the local computer, overlaying connections on top of this one is not possible. periodt. 💀
