qmi_decode_basic_elem 💅

okay bestie, welcome to the qmi_decode_basic_elem(9) page — yes that's the section 9 kernel API manual, we're in the drivers/soc/qcom part of the tree and honestly it's giving main character energy. sit down, drink some water, let's decode some elements ✨

✨ NAME ✨

qmi_decode_basic_elem — decodes elements of basic/primary data type 🎀

🌸 SYNOPSIS 🌸

int qmi_decode_basic_elem (void *buf_dst , const void *buf_src , u32
elem_len , u32 elem_size );

like yes, four args, all of them matter, no cap 💅

🦋 ARGUMENTS 🦋

  • buf_dst — the buffer where the decoded element goes. it's the destination, the place we're landing, the whole point 🫶
  • buf_src — the buffer holding the elements in QMI wire format. this is where the info currently lives, in its little encoded form 😭
  • elem_len — how many elements we're decoding. like the count, not the size, don't get it twisted 💀
  • elem_size — the size of a single instance of the element being decoded. one (1) element's worth of bytes, periodt ⭐

🧚 DESCRIPTION 🧚

so this function decodes "elem_len" number of elements — in QMI wire format, each one "elem_size" bytes big — out of the source buffer "buf_src", and stores the decoded versions into the destination buffer "buf_dst". literally that's the whole job 🎀

the elements are of primary data type, which includes u8 - u64 or similar. so like, the basic little guys, not structs, not strings, just the primary types being iconic 💜

and when it's done, the function returns the number of bytes of decoded information. so you get a size back, bestie, that's your receipt 🔥

👑 RETURN 👑

on success: the total size of the decoded data elements, in bytes 🌈

on error: a negative errno. so if you see a negative number, that's not a size, that's a warning sign, do not pass go 😭

💖 SEE ALSO 💖

like the whole encdec friend group, honestly obsessed 🫶✨
