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.
