fc_exch_ptr_get(9)

🌸 fc_exch_ptr_get(9) 🌸

okay bestie, welcome to the Kernel API Manual entry for fc_exch_ptr_get(9) — title and manual name folded right in at the top, cute, we love a tidy intro. it’s giving “tiny helper, big exchange-pool energy,” and we’re gonna read it together. 💅✨

💖 NAME 💖

fc_exch_ptr_get — return an exchange from an exchange pool. periodt. 🎀

🦋 SYNOPSIS 🦋

struct fc_exch * fc_exch_ptr_get (struct fc_exch_pool *pool , u16 index
);

🍓 ARGUMENTS 🍓

• pool — the Exchange Pool you’re getting an exchange from. it’s the source, the stash, the little exchange neighborhood. 🫶
• index — the index of the exchange within the pool. literally the number that says “this one, bestie.” 🔥

💜 DESCRIPTION 💜

okay so here’s the whole vibe: use the index to get an exchange from within an exchange pool. exches will point to an array of exchange pointers. the index will select the exchange within the array. that’s it, that’s the function, no cap. ✨
