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

: the rs control structure

data

: data field of a given type

par

: received parity data field

len

: data length

: 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.
