zl3073x_fw_load(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ zl3073x_fw_load β€” load ALL the components, bestie ✨

okay so this is a page from the Kernel API Manual (section 9, drivers-and-kernel-stuff energy), and it's about one very specific little function called zl3073x_fw_load. it's giving "firmware loader that does exactly what it says on the tin" πŸ’…


🌸 SYNOPSIS 🌸

struct zl3073x_fw * zl3073x_fw_load (struct zl3073x_dev *zldev , const
       char *data , size_t size , struct netlink_ext_ack *extack );

like, four arguments, one return, zero drama (well, some drama, because it can return an error pointer β€” more on that in a sec 🫢)


πŸŽ€ ARGUMENTS πŸŽ€

  • zldev β€” the zl3073x device structure. this is your device bestie, the whole reason we're here πŸ’–
  • data β€” source buffer pointer. yes, it's a pointer, yes it's const char *, no you may not scribble on it πŸ”₯
  • size β€” the size of that source buffer. pls keep it honest, it's size_t and it matters ✨
  • extack β€” netlink extack pointer, and its whole job is to report errors. it's the friend who tells everyone what went wrong at the function's worst moment 😭

πŸ¦‹ DESCRIPTION πŸ¦‹

so the function does two things, and it's literally right there in the name if you squint:

  1. it allocates the firmware structure πŸ‘‘
  2. it loads all components from the given buffer β€” the one specified by data and size πŸ’«

that's it. that's the whole vibe. "all components" means all of them β€” no partial little treat, no skipping the boring ones. main character energy only πŸ’…


⭐ RETURN ⭐

  • on success? you get a pointer to firmware πŸŽ‰
  • on error? you get an error pointer, not NULL. so like, check it with IS_ERR()-style thinking, not == NULL thinking. no cap πŸ™ˆ
fr fr, an error pointer is still a pointer, so don't go dereferencing it and acting surprised. the extack is the one that carries the actual error gossip πŸ’€

and it's friends with the whole little squad:

like, one big happy firmware family πŸ“
