🌸 NAME 🌸

okay so this is the flat_xor_hd.c(3) page from liberasurecode, and bestie the NAME is literally this path:

/build/source/src/backends/xor/flat_xor_hd.c

✨ SYNOPSIS ✨

#include <stdio.h>
#include <stdlib.h>
#include <xor_code.h>
#include 'erasurecode.h'
#include 'erasurecode_backend.h'
#include 'erasurecode_helpers.h'

🧚 Data Structures 🧚

struct flat_xor_hd_descriptor — the struct bestie, that's the one 💅

🎀 Macros 🎀

#define FLAT_XOR_LIB_MAJOR 1
#define FLAT_XOR_LIB_MINOR 0
#define FLAT_XOR_LIB_REV 0
#define FLAT_XOR_LIB_VER_STR '1.0'

#define DEFAULT_W 32

🦋 Typedefs 🦋

typedef xor_code_t *(* init_xor_hd_code_func) (int, int, int)
typedef void(* xor_code_encode_func) (xor_code_t *, char **, char **, int)
typedef int(* xor_code_decode_func) (xor_code_t *, char **, char **, int *, int, int)
typedef int(* xor_hd_fragments_needed_func) (xor_code_t *, int *, int *, int *)

💅 Functions 💅

static int flat_xor_hd_encode (void *desc, char **data, char **parity, int blocksize) — exact signature, no cap ✨
static int flat_xor_hd_decode (void *desc, char **data, char **parity, int *missing_idxs, int blocksize) — here it is, character for character 🫶
static int flat_xor_hd_reconstruct (void *desc, char **data, char **parity, int *missing_idxs, int destination_idx, int blocksize) — locked in 💖
static int flat_xor_hd_check_reconstruct_fragments (void *desc, int *missing_idxs, int destination_idx) — yup, this whole signature 🌸
static int flat_xor_hd_min_fragments (void *desc, int *missing_idxs, int *fragments_to_exclude, int *fragments_needed) — the fragments-needed one 🎀
static int flar_xor_hd_element_size (void *desc) — returns the element-size, which is the number of bits stored on a given device, per codeword. (Yes bestie, flar is written exactly like that in the source, periodt 💀)
static void * flat_xor_hd_init (struct ec_backend_args *args, void *sohandle) — init signature, slay ✨
static int flat_xor_hd_exit (void *desc) — exit signature 🦋
static bool flat_xor_is_compatible_with (uint32_t version) — compatibility check signature 👑
__attribute__ ((visibility('internal'))) — this icon right here 💅
