idpf_ptp_get_cross_time(9)

✨ idpf_ptp_get_cross_time ✨

okay bestie so this one's from the Kernel API Manual (kernel 9, section 9, very demure, very get cross time) and it's literally just one little function that goes and asks the hardware what time it thinks it is 🕰️✨

💖 NAME 💖

idpf_ptp_get_cross_time — sends the virtchnl get cross time message 🎀

🦋 SYNOPSIS 🦋

int idpf_ptp_get_cross_time (struct idpf_adapter *adapter , struct
idpf_ptp_dev_timers *cross_time );

🌸 ARGUMENTS 🌸

• adapter — the driver-specific private structure, aka the little home base for this driver 🏠
• cross_time — pointer to the device clock structure, and that's exactly where the value gets set 🫶

🔥 DESCRIPTION 🔥

so basically what happens is: it sends the virtchnl get cross time message, and that message's whole job is to grab the time of the clock and the system time. two times. one message. iconic behavior honestly 👑

⭐ RETURN ⭐

0 on success, -errno otherwise. that's it, that's the whole vibe check 💅
