uclogic_par...it_with_desc β Kernel API Manual β¨
okay so bestie, welcome to the ~kernel~ side of things. this one is a lil C function from the Kernel API Manual, filed under that legendary abbreviated title uclogic_par...it_with_desc(9) (yes the truncation is real, we love an ellipsis moment π). she's a nine-er, she's a little niche, and she's literally the function that gives your tablet's frame controls an actual identity via a static report descriptor. let's get into it π¦
β¨ NAME β¨
uclogic_params_frame_init_with_desc β initializes the tablet's frame control parameters</> using a static report descriptor</>. that's the whole vibe: params for the frame, plus a descriptor you hand over yourself. no cap π
πΈ SYNOPSIS πΈ
int uclogic_params_frame_init_with_desc (struct uclogic_params_frame
*frame , const __u8 *desc_ptr , size_t desc_size , unsigned int id );
look at her go π four whole arguments, one tidy int coming back. signature's copied exactly, so don't come for me about the spacing β that's how the original rocked it β¨
π ARGUMENTS π
frameβ pointer to the frame parameters you're about to initialize, and heads up, this is the one you'll later clean up withuclogic_params_frame_cleanup. if things go sideways and it errors out, this thing stays untouched β not modified in case of error, king behavior fr fr π. also: cannot beNULL, hard no, don't even try πdesc_ptrβ the report descriptor pointer. she's allowed to beNULL, but only ifdesc_sizeis zero. it's giving conditional freedom π¦desc_sizeβ the size of that report descriptor. yep, thesize_tone πidβ the report ID used for frame reports, if they should be tweaked. if they shouldn't be tweaked, it's zero. zero = no tweaking, periodt β¨
β RETURN β
returns zero when everything went slay π and a negative errno code on error π that's the whole contract, no extra lore.
quick vibe check bestie β don't forgetframecan't beNULLand stays unmodified when it errors. those are the facts, no guessing π«Ά
