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.
