/build/sourc...xor_hd_code.c(3)

🎀 NAME 🎀

Ok bestie, welcome to the liberasurecode manual page for /build/sourc...xor_hd_code.c(3) — the actual file under the microscope is /build/source/src/builtin/xor_codes/xor_hd_code.c. 💅✨

🌸 SYNOPSIS 🌸

You gotta pull in these headers first, no cap:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include 'xor_code.h'
#include 'xor_hd_code_defs.h'

int xor_hd_fragments_needed (xor_code_t * code_desc, int *

    fragments_needed)

Re-visit this decision (KMG): this is non-optimal, but good enough in most cases. If there is a single data item to reconstruct, then try to find a connected parity with no items in fragments_to_exclude. If there is a single parity item to reconsturct — that spelling is literally in the original, bestie 😭 — or more than 1 data/parity element missing, then just work fragments_to_exclude into missing_idxs.

There is either more than one failed element, a failed parity element or we were unable to return the fragments needed for a simple reconstruction.

Add everything to missing_idxs (basically, give up on optimizing).
