NAME decode_rs8 - Decode codeword (8bit data width)

SYNOPSIS int decode_rs8(struct rs_control * rs, uint8_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 The syndrome and parity uses a uint16_t data type to enable symbol size > 8. The calling code must take care of decoding of the syndrome result and the received parity before calling this code. Returns the number of corrected bits or -EBADMSG for uncorrectable errors.
