lpfc_link_state_show(9)

💖 lpfc_link_state_show — your Kernel API Manual moment, bestie ✨

okay so this is lpfc_link_state_show(9) from the Kernel API Manual, and it’s literally here to tell you the link state of the port. that’s the whole vibe 🦋

🌸 NAME 🌸

lpfc_link_state_show — Return the link state of the port 💅

🎀 SYNOPSIS 🎀

ssize_t lpfc_link_state_show (struct device *dev , struct
       device_attribute *attr , char *buf );

✨ ARGUMENTS ✨

• dev — class converted to a Scsi_host structure. yes, it’s giving “device but make it SCSI host” 💖
• attr — device attribute, not used. she’s just there, iconic but unemployed 🫶
• buf — on return contains text describing the state of the link. so after the call, this is where the link-state lore lives ✨

💀 NOTES 💀

ngl, the switch statement has no default, so zero will be returned. no cap.

🔥 RETURN 🔥

size of formatted string. that’s it, that’s the return value 💖
