idpf_ptp_re..._reg_mailbox(9)

💅 NAME 💅

okay so bestie, this page comes from the Kernel API Manual, and it’s about idpf_ptp_read_src_clk_reg_mailbox — Read the main timer value through mailbox. The header is all truncated like idpf_ptp_re..._reg_mailbox(9) (the middle is literally hiding), but the function name is the full one. iconic.

✨ SYNOPSIS ✨

int idpf_ptp_read_src_clk_reg_mailbox (struct idpf_adapter *adapter ,
       struct ptp_system_timestamp *sts , u64 *src_clk );

🎀 ARGUMENTS 🎀

• adapter — driver specific private structure. It’s the driver’s own private little structure, lowkey essential to the whole vibe.
• sts — optional parameter for holding a pair of system timestamps from the system clock. Will be ignored when NULL is given. So if NULL shows up, it gets ignored — not me being optional and unbothered.
• src_clk — returned main timer value in nanoseconds unit. This is where the main timer value comes back, in nanoseconds, periodt.

🦋 RETURN 🦋

0 on success, -errno otherwise. Zero is the success slay; -errno is the error-code plot twist.
