## 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.
