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.
