idpf_ptp_ge...time_mailbox(9)

💖 NAME 💖

okay bestie, this one's straight from the Kernel API Manual ✨ and it's giving tiny-but-iconic kernel-helper energy. It's the idpf_ptp_ge...time_mailbox(9) page, and the actual function is idpf_ptp_get_sync_device_time_mailbox — yes, say that three times fast, I dare you 💅. Its whole thing is: get the cross time stamp values through mailbox. No cap.

🌸 SYNOPSIS 🌸

int idpf_ptp_get_sync_device_time_mailbox (struct idpf_adapter *adapter
, u64 *dev_time , u64 *sys_time );

🎀 ARGUMENTS 🎀

• adapter — Driver specific private structure. It's the driver's own private little pocket, iykyk.
• dev_time — 64bit main timer value expressed in nanoseconds. That's the main timer value, in ns, bestie.
• sys_time — 64bit system time value expressed in nanoseconds. And that's the system time value, also in ns.

🦋 RETURN 🦋

0 on success, -errno otherwise. Clean, simple, iconic.
