πŸ’– cs_dsp_find_alg_region(9) πŸ’–

okay so this is a page from the Kernel API Manual, and honestly? it's a little cutie. it does exactly one thing and it does it slayfully: it goes looking for an algorithm region that matches what you asked for. that's it. that's the whole vibe. πŸ¦‹


✨ NAME ✨

cs_dsp_find_alg_region β€” finds a matching algorithm region πŸ”πŸ’…


🌸 SYNOPSIS 🌸

struct cs_dsp_alg_region * cs_dsp_find_alg_region (struct cs_dsp *dsp ,
int type , unsigned int id );

like, yes, it's a mouthful, but it's giving "one function, three args, no drama" and we love that for it 🫢


πŸŽ€ ARGUMENTS πŸŽ€

  • dsp β€” pointer to the DSP structure. this is your main character, the whole context you're digging around in πŸ’œ
  • type β€” the algorithm type to match. you're like "bestie, find me one shaped like this" 🧚
  • id β€” the algorithm id to match. and also with this number on it. two filters, one search, iconic ⭐

πŸ”₯ RETURN πŸ”₯

a pointer to the matching algorithm region πŸ’– β€” or NULL if nothing matched. no match, no problem, just NULL. don't forget to check it, ngl 😭
