Implement two new functions to report the total data stored accross the whole buffer and the data stored at a specific offset until the next gap or the buffer end. To facilitate implementation of these new functions and also future add/delete operations, a new abstraction is introduced : ncb_blk. This structure represents a block of either data or gap in the buffer. It simplifies operation when moving forward in the buffer. The first buffer block can be retrieved via ncb_blk_first(buf). The block at a specific offset is accessed via ncb_blk_find(buf, off). This abstraction is purely used in functions but not stored in the ncbuf structure per-se. This is necessary to keep the minimal memory footprint.
The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - BRANCHES to understand the project's life cycle and what version to use - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
