AVSystem Commons Library
A set of common code used in AVSystem for projects written in C.
Currently the included components are:
- Data structures
avs_buffer- simple data buffer with circular-like semantics
avs_list- lightweight, generic and type-safe implementation of a singly linked list, with API optimized for ad-hoc usage
avs_rbtree- basic implementation of a red-black binary search tree
avs_vector- generic implementation of a C++-style vector (dynamic array)
- Networking framework
- Other modules
avs_algorithm- currently contains a base64 encoder and decoder
avs_log- simple logging framework
avs_stream- generic framework for I/O streams; includes pre-implemented streams that can be used through its unified API:
md5.h- calculating MD5 hashes
netbuf.h- buffered network I/O
stream_file.h- file I/O
stream_inbuf.h- read-only wrapper for raw memory buffers
stream_membuf.h- in-memory stream optimized for a single-message write-then-read cycle
stream_outbuf.h- write-only wrapper for raw memory buffers
avs_unit- simple and easy to use unit testing framework
avs_utils- currently contains utility function for handling time values, psudorandom number generation and string tokenization
Most of the library is written in standard and portable C99. There are some dependencies on POSIX APIs, but there are provisions for replacing them when necessary (see the
compat directory for details).
avs_unit relies on some GCC-isms and is unlikely to work with any compiler that is not based on either GCC or Clang.
