Library Internals: How the library deals with errors

This document is intended to be informative and not authoritative. The library may change its internal behavior regarding error handling without notice.

This document describes how the library internally deals with errors, so that you can get a better idea of what may be happening when debugging various issues.

libcouchbase - The C Couchbase Client Library

The C library provides an interface to the Couchbase Cluster from a C application. It is used by many of our client libraries as lower layer which performs network I/O and protocol handling. It may also be used as a standalone client.

The library is known to function on Linux, Mac OS X and Windows. Other platforms may be work but are not routinely tested.

LIBCOUCHBASE BUILD CONFIGURATION

lcbutils

This component contains a collection of utilities for libcouchbase which do not require external or I/O dependencies. This should always be first and be assumed to be the base dependency of other libraries.

It will be built as a static library and linked in with the resultant DSO, so that its symbols are not duplicated twice.
