ib_cm_listen(9)

🌸 NAME 🌸

ib_cm_listen(9) — bestie, this Kernel API Manual baddie initiates listening on the specified service ID for connection requests and service ID resolution requests. It's giving “open the door, the requests are coming” energy. 💖✨

✨ SYNOPSIS ✨

int ib_cm_listen (struct ib_cm_id *cm_id , __be64 service_id );

🎀 ARGUMENTS 🎀

• cm_id — the connection identifier associated with the listen request. It's the handle for this whole listening moment, periodt. 🫶
• service_id — the service identifier matched against incoming connection requests and service ID resolution requests. It should be specified in network-byte order, fr fr. And if it's set to IB_CM_ASSIGN_SERVICE_ID, the CM will assign a service ID to the caller — cute, right? 💅
