This module implements the BER - encoding rules. Documentation is found in the files odr-use.man - and odr.txt. - -asn - This module implements the Z39.50/SR protocol. The best way - to find out how it works is to look in the sample - client/server code in server/seshigh.c or yazlib/tst.c. The - interface is still wholly described by the file proto.h - which defines structure and type definitions for each of the - types introduced in the protocol specification. - -comstack- This module implements the transport transparency - stack (COMSTACK). The comstack implements a generic interface - for exchanging BER-encoded records over a network. It supports - the 'American' mode of exchanging the records straight over - TCP/IP, and uses Peter Furniss' XTIMOSI package over RFC1006. - Look for documentation in the file comstack.man. - -rfc1006 - Xtimosi requires an implementation of the OSI transport - layer with an XTI-based API. Some systems (HP and DEC, - notably) provide this. For others, we provide an - implementation of the RFC1006 protocol (which is what - ISODE-based implementations often use). This module is not - neeeded if you don't use xtimosi, and it's not included in the - libyaz.a library. - -server - This is the implementation of the server frontend. It - provides event-handling and server managament functions, - and calls the backend primitives (best documentation of these - is in the file include/backend.h).
