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.
