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

rs

the rs control structure

data

data field of a given type

par

received parity data field

len

data length

s

syndrome data field (if NULL, syndrome is calculated)

no_eras

number of erasures

eras_pos

position of erasures, can be NULL

invmsk

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

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.
