nCore

nCore is an efficient and portable C++ library for
developers. It includes a set of several satellite
C++ classes to perform threading, file I/O (with
endian-awareness), networking (TCP, UDP, IPv4, and
IPv6), high-perf timing, easy logging with
pluggable sinks, memory allocation debugging,
hashing (MD5, string, CRC32, CRC16, and CRC8),
loading of dynamic libraries (shared objects),
dog-tagging (your final application/library binary
file(s)), handling wide string manipulation
methods through a single class (StringA), and
more. Each of those features can be turned off at
compile-time to make the final binary file smaller.
