NAME

       encode_rs16 - Calculate the parity for data values (16bit data width)

SYNOPSIS

       int encode_rs16(struct rs_control * rs, uint16_t * data, int len, uint16_t * par, uint16_t invmsk);

ARGUMENTS

       rs
	   the rs control structure

       data
	   data field of a given type

       len
	   data length

       par
	   parity data, must be initialized by caller (usually all 0)

       invmsk
	   invert data mask (will be xored on data, not on parity!)

DESCRIPTION

       Each field in the data array contains up to symbol size bits of valid data.

NAME

       parchive - RAID like data recovery for PAR ver 1.0 files

DESCRIPTION

       The  idea  behind  the parchive is to provide a tool to apply the data-recovery capability concepts of RAID-like systems to the posting and
       recovery of multi-part archives on Usenet. Current filespec and clients support the volumes for 'X' parity volumes present.

       The key to this mission is a clean file format specification which provides all the necessary capabilities for programs	to  easily  verify
       and regenerate single missing parts out of a set of archives.

       We might just be able to make binary posting and downloading on Usenet a little easier. That's a pretty cool goal!

       Note  that  parchive supports the old legacy version 1.0 PAR format.  For new projects, use the par2 package which supports the version 2.0
       PAR format which provides superior features.

       This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

USAGE

       parchive c(heck) [options] <par file>
	      Check parity archive

       parchive r(ecover) [options] <par file>
	      Restore missing volumes

       parchive a(dd) [options] <par file> [files]
	      Add files to parity archive

       parchive m(ix) [options]
	      Try to restore from all parity files at once

       parchive i(nteractive) [<par files>]
	      Interactive mode (very bare-bones)

       Options: (Can be turned off with '+')

       -m     Move existing files out of the way

       -f     Fix faulty filenames

       -p<n>  Number of files per parity volume

       -n<n>  Number of parity volumes to create

       -d     Search for duplicate files

       -k     Keep broken files

       -s     Be smart if filenames are consistently different.

       +i     Do not add following files to parity volumes

       +c     Do not create parity volumes

       +C     Ignore case in filename comparisons

       +H     Do not check control hashes

       -v,+v  Increase or decrease verbosity

       -h,-?  Display this help

       --     Always treat following arguments as files
