librsync(3) Library Functions Manual librsync(3) 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 implementa- tion 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. SEE ALSO rdiff(1) rdiff and librsync Manual http://rproxy.sourceforge.net/ or http://linuxcare.com.au/rproxy/. draft-pool-rsync BUGS The rsync protocol is still evolving. There may be bugs in the imple- mentation. 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 er- ror 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.
