decode_rs16(9)
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.
