pccard_loop_tuple(9)

💖 NAME 💖

pccard_loop_tuple — loop over tuples in the CIS. This one's from the Kernel API Manual (and yes, bestie, this is pccard_loop_tuple(9) 💅), and it's literally the helper that walks the CIS like it's strutting down a runway ✨🦋.

🌸 SYNOPSIS 🌸

int pccard_loop_tuple (struct pcmcia_socket *s , unsigned int function ,
cisdata_t code , cisparse_t *parse , void *priv_data , int (*loop_tuple)
(tuple_t *tuple, cisparse_t *parse, void *priv_data) );

🎀 ARGUMENTS 🎀

• s — the struct pcmcia_socket where the card is inserted 💳 (yes, the socket, keep up 😌)
• function — the device function we loop for 🔁
• code — which CIS code shall we look for? 🔎
• parse — buffer where the tuple shall be parsed (or NULL, if no parse) 🫧
• priv_data — private data to be passed to the loop_tuple function 🎒
• loop_tuple — function to call for each CIS entry of type function. IT gets passed the raw tuple, the paresed tuple (if parse is set — yes bestie, that's the source's spelling 😭) and priv_data ✨

🔥 DESCRIPTION 🔥

Okay so bestie, pccard_loop_tuple loops over all CIS entries of type function, and calls the loop_tuple function for each entry. If the call to loop_tuple returns 0, the loop exits — periodt 💅. Returns 0 on success or errorcode otherwise.

The callback returning 0 is the stop signal 🛑 — that's the whole vibe check. The function itself returns 0 on success or errorcode otherwise, no cap.
