NAME

       librsync - library for delta compression of streams

SYNOPSYS

        #include <stdio.h>
        #include <stdlib.h>
        #include <librsync.h>

        cc ... -lrsync

DESCRIPTION

       The  librsync  library  implements  network  delta-compression  of streams and files.  The
       algorithm is similar to that used in the rsync(1) and xdelta(2) programs, but  specialized
       for  transfer of arbitrary-length octet streams.  Unlike most diff programs, librsync does
       not require access to both of the files on the same  machine,  but  rather  only  a  short
       ``signature'' of the old file and the complete contents of the new file.

       The  canonical  use  of librsync is in the rproxy(8) reference implementation of the rsync
       proposed extension to HTTP.  It may be useful to other programs which wish  to  do  delta-
       compression  in  HTTP,  or  within  their  own  protocol.  There are HTTP-specific utility
       functions within librsync, but they need not be used.

       A number of tools such as rdiff(1) provide command-line and  scriptable  access  to  rsync
       functions.

BUGS

       The  rsync  protocol  is  still  evolving.   There may be bugs in the implementation.  The
       interface may change in the future, but it is becoming more stable.

       Many routines will panic in case of error rather than  returning  an  error  code  to  the
       caller.  Patches to fix this are welcome, but at the current state of development aborting
       seems as useful as trusting to possibly-incomplete checking in the client.
