pcmcia_loop_tuple(9)

💖 pcmcia_loop_tuple(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this one is all about looping over tuples in the CIS, and it is lowkey iconic 🎀

🌸 NAME 🌸

pcmcia_loop_tuple — loop over tuples in the CIS 💅

✨ SYNOPSIS ✨

int pcmcia_loop_tuple (struct pcmcia_device *p_dev , cisdata_t code ,
int (*loop_tuple) (struct pcmcia_device *p_dev, tuple_t *tuple, void
*priv_data) , void *priv_data );

🎀 ARGUMENTS 🎀

• p_dev — the struct pcmcia_device which we need to loop for. like, this is the device we're digging through, no cap 🫶
• code — which CIS code shall we look for? bestie, you gotta pick one 🔍
• loop_tuple — function to call for each CIS entry of type function. IT gets passed the raw tuple and priv_data. yes queen, every single entry gets the callback treatment 💖
• priv_data — private data to be passed to the loop_tuple function. your lil backpack of extra info 🎒

🦋 DESCRIPTION 🦋

pcmcia_loop_tuple loops over all CIS entries of type function, and calls the loop_tuple function for each entry. so it's literally going one by one and handing each entry to your callback ✨

if the call to loop_tuple returns 0, the loop exits. that's the stop signal, bestie 🛑

returns 0 on success or errorcode otherwise. so 0 is the slay outcome, and anything else is giving error 😭
