💖 lpfc_wwn_set(9) 💖

okay bestie, this is the Kernel API Manual page for lpfc_wwn_set(9), and it is literally here to convert a string into the 8 byte WWN value. no cap, the main character energy is real. 💅✨

🌸 NAME 🌸

lpfc_wwn_set — Convert string to the 8 byte WWN value.

🦋 SYNOPSIS 🦋

the signature is giving:

size_t lpfc_wwn_set (const char *buf , size_t cnt , char wwn[] );

🎀 ARGUMENTS 🎀

• buf — WWN string. that's the string itself, bestie.
• cnt — Length of string. lowkey important.
• wwn — Array to receive converted wwn value. the destination, periodt.

💀 RETURN 💀

return vibe check:

• -EINVAL — if the buffer does not contain a valid wwn.
• 0 — success.
