decode_rs8(9)
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.
