DECODE_RS16(9) Public Functions Provided DECODE_RS16(9)

NAME

decode_rs16 - Decode codeword (16bit data width)

SYNOPSIS

int decode_rs16(struct rs_control * rs, uint16_t * data, uint16_t * par, int len, uint16_t * s, int no_eras, int * eras_pos, uint16_t invmsk, uint16_t * corr);

ARGUMENTS

struct rs_control * rs

the rs control structure

uint16_t * data

data field of a given type

uint16_t * par

received parity data field

int len

data length

uint16_t * s

syndrome data field (if NULL, syndrome is calculated)

int no_eras

number of erasures

int * eras_pos

position of erasures, can be NULL

uint16_t invmsk

invert data mask (will be xored on data, not on parity!)

uint16_t * corr

buffer to store correction bitmask on eras_pos

DESCRIPTION

Each field in the data array contains up to symbol size bits of valid data. Returns the number of corrected bits or -EBADMSG for uncorrectable errors.
