  Description: In an ideal world, Assuan is irrelevant. Assuan's primary use is to allow a client to interact with a non-persistent server. Using Assuan, this is accomplished by forking a subprocess and communicating with it via, for example, a pipe or unix domain socket. This method is neither elegant nor efficient especially when there is a lot of data spread across several transactions: not only is there a penalty for an increased number of context switches, but also a significant amount of data is MEMCPYed from the client to a file descriptor and from the file descriptor to the server.

  Description: This is an implementation of double-array structure for representing trie, as proposed by Junichi Aoe. Trie is a kind of digital search tree, an efficient indexing method in which search time is independent of database size. It only takes O(m) search time, where m is the length of the search string. Comparably as efficient as hashing, trie also provides flexibility on incremental matching and key spelling manipulation. This makes it ideal for lexical analyzers, as well as spelling dictionaries.

  Description: Libdnsres provides a non-blocking thread-safe API for resolving DNS names. It requires that your main application is built on top of libevent. Libdnsres' API essentially mirrors the traditional gethostbyname and getaddrinfo interfaces. All return values have been replaced by callbacks instead. The code borrows heavily from the BSD resolver library. In fact, it is an extremely ugly hack to make the BSD resolver library non-blocking and thread-safe without changing the API too much.

• dev-libs/libffi::gentoo - Ebuilds: 8, Stable: 3.5.2, Testing: 3.8.0, Snapshot: 9999
  Description: Compilers for high level languages generate code that follow certain conventions. These conventions are necessary, in part, for separate compilation to work. One such convention is the "calling convention". The "calling convention" is essentially a set of assumptions made by the compiler about where function arguments will be found on entry to a function. A "calling convention" also specifies where the return value for a function is found. Some programs may not know at the time of compilation what arguments are to be passed to a function. For instance, an interpreter may be told at run-time about the number and types of arguments used to call a given function. Libffi can be used in such programs to provide a bridge from the interpreter program to compiled code. The libffi library provides a portable, high level programming interface to various calling conventions. This allows a programmer to call any function specified by a call interface description at run time. Ffi stands for Foreign Function Interface. A foreign function interface is the popular name for the interface that allows code written in one language to call code written in another language. The libffi library really only provides the lowest, machine dependent layer of a fully featured foreign function interface. A layer must exist above libffi that handles type conversions for values passed between the two languages.

• dev-libs/libpcl::xdch47 - Ebuilds: 1, Stable: 1.12, Testing: 1.12
  Description: The Portable Coroutine Library (PCL) implements the low level functionality for coroutines. For a definition of the term coroutine see The Art of Computer Programming by Donald E. Knuth. Coroutines are a very simple cooperative multitasking environment where the switch from one task to another is done explicitly by a function call. Coroutines are a lot faster than processes or threads switch, since there is no OS kernel involvement for the operation. Also coroutines require much less OS resources than processes of threads. The idea of writing this library started when I was testing Linux epoll functionality and performance. I initially started using the coro library by E. Toernig &lt;froese@gmx.de&gt; and I found the library very interesting. It was simple and yet powerful. The limitations of the coro library were both non portability and crashes when not used together with certain versions of gcc. So I decided to write a new library to address the problems aforementioned by also taking portable context switching ideas from the GNU Pth library. This library is easily portable on almost every Unix system and on Windows. It can use either the ucontext.h functionalities ( getcontext()/makecontest()/swapcontext() ) or the standard longjmp()/setjmp().

  Description: SLZ is a fast and memory-less stream compressor which produces an output that can be decompressed with zlib or gzip. It does not implement decompression at all, zlib is perfectly fine for this. The purpose is to use SLZ in situations where a zlib-compatible stream is needed and zlib's resource usage would be too high while the compression ratio is not critical. The typical use case is in HTTP servers and gateways which have to compress many streams in parallel with little CPU resources to assign to this task, and without having to throttle the compression ratio due to the memory usage. In such an environment, the server's memory usage can easily be divided by 10 and the CPU usage by 3

  Description: LibTomMath is a free open source portable number theoretic multiple-precision integer library written entirely in C. (phew!). The library is designed to provide a simple to work with API that provides fairly efficient routines that build out of the box without configuration. The library builds out of the box with GCC 2.95 [and up] as well as Visual C++ v6.00 [with SP5] without configuration. The source code is arranged to make it easy to dive into a particular area very quickly. The code is also littered with comments [This is one of the on going goals] that help explain the algorithms and their implementations. Ideally the code will serve as an educational tool in the future for CS students studying number theory. The library provides a vast array of highly optimized routines from various branches of number theory. * Simple Algebraic o Addition o Subtraction o Multiplication o Squaring o Division * Digit Manipulation o Shift left/right whole digits (mult by 2b by moving digits) o Fast multiplication/division by 2 and 2k for k&gt;1 o Binary AND, OR and XOR gates * Modular Reductions o Barrett Reduction (fast for any p) o Montgomery Reduction (faster for any odd p) o DR Reduction (faster for any restricted p see manual) o 2k Reduction (fast reduction modulo 2p - k) o The exptmod logic can use any of the four reduction algorithms when appropriate with a single function call. * Number Theoretic o Greatest Common Divisor o Least Common Multiple o Jacobi Symbol Computation (falls back to Legendre for prime moduli) o Multiplicative Inverse o Extended Euclidean Algorithm o Modular Exponentiation o Fermat and Miller-Rabin Primality Tests, utility function such as is_prime and next_prime * Miscellaneous o Root finding over Z o Pseudo-random integers o Signed and Unsigned comparisons * Optimizations o Fast Comba based Multiplier, Squaring and Montgomery routines. o Montgomery, Diminished Radix and Barrett based modular exponentiation. o Karatsuba and Toom-Cook multiplication algorithms. o Many pointer aliasing optimizations throughout the entire library.

  Description: Text files are nowadays usually encoded in Unicode, and may consist of very different scripts – from Latin letters to Chinese Hanzi –, with many kinds of special characters – accents, right-to-left writing marks, hyphens, Roman numbers, and much more. But the POSIX platform APIs for text do not contain adequate functions for dealing with particular properties of many Unicode characters. In fact, the POSIX APIs for text have several assumptions at their base which don't hold for Unicode text. This library provides functions for manipulating Unicode strings and for manipulating C strings according to the Unicode standard.

This is for example when using background images helpful because the environment of the dynamic data / graphics is not constantly recalculated got to. All three screens will appear "on top of each other" on the LCD and will go through previously defined parameters (LUI_LCDmode ()) corresponding to each other bitwise connected. The coordinate origin (x = 0, y = 0) of a screen is always in the left upper corner. In addition, the inversion and the rotation of the screens supports (90 ° steps), while saving the programmer the coordinates conversions stay.

• dev-libs/miniz::gentoo - Ebuilds: 3, Stable: 3.0.2, Testing: 3.1.2
  Description: Miniz is a lossless, high performance data compression library in a single source file that implements the zlib (RFC 1950) and Deflate (RFC 1951) compressed data format specification standards. It supports the most commonly used functions exported by the zlib library, but is a completely independent implementation so zlib's licensing requirements do not apply. Miniz also contains simple to use functions for writing .PNG format image files and reading/writing/appending .ZIP format archives. Miniz's compression speed has been tuned to be comparable to zlib's, and it also has a specialized real-time compressor function designed to compare well against fastlz/minilzo.

  Description: The Raspberry Pi Pico SDK (henceforth the SDK) provides the headers, libraries and build system necessary to write programs for the RP2040-based devices such as the Raspberry Pi Pico in C, C++ or assembly language. The SDK is designed to provide an API and programming environment that is familiar both to non-embedded C developers and embedded C developers alike. A single program runs on the device at a time and starts with a conventional `main()` method. Standard C/C++ libraries are supported along with C level libraries/APIs for accessing all of the RP2040's hardware include PIO (Programmable IO). Additionally the SDK provides higher level libraries for dealing with timers, synchronization, USB (TinyUSB) and multi-core programming along with various utilities. The SDK can be used to build anything from simple applications, to fully fledged runtime environments such as MicroPython, to low level software such as RP2040's on-chip bootrom itself. Additional libraries/APIs that are not yet ready for inclusion in the SDK can be found in [pico-extras](https://github.com/raspberrypi/pico-extras).

  Description: POCO, the C++ Portable Components, is a collection of open source C++ class libraries that simplify and accelerate the development of network-centric, portable applications in C++. The libraries integrate perfectly with the C++ Standard Library and fill many of the functional gaps left open by it. Their modular and efficient design and implementation makes the C++ Portable Components extremely well suited for embedded development, an area where the C++ programming language is becoming increasingly popular, due to its suitability for both low-level (device I/O, interrupt handlers, etc.) and high-level object-oriented development. Of course, POCO is also ready for enterprise-level challenges. The POCO libraries free developers from re-inventing the wheel, and allow them to spend their time on more worthwhile areas, such as getting things done quickly and working on the features that make their application unique.

  Description: StarPU is a runtime system that offers support for heterogeneous multicore machines. While many efforts are devoted to design efficient computation kernels for those architectures (e.g. to implement BLAS kernels on GPUs or on Cell's SPUs), StarPU not only takes care of offloading such kernels (and implementing data coherency across the machine), but it also makes sure the kernels are executed as efficiently as possible.

• dev-libs/stfl::gentoo - Ebuilds: 1, Stable: 0.24, Testing: 0.24
  Description: STFL is a library which implements a curses-based widget set for text terminals. The STFL API can be used from C, SPL, Python, Perl and Ruby. Since the API is only 14 simple function calls big and there are already generic SWIG bindings it is very easy to port STFL to additional scripting languages. A special language (the Structured Terminal Forms Language) is used to describe STFL GUIs. The language is designed to be easy and fast to write so an application programmer does not need to spend ages fiddling around with the GUI and can concentrate on the more interesting programming tasks.

  Description: The C++ Actor Framework (CAF) as forked and pinned by Zeek's Broker messaging library (github.com/zeek/actor-framework). It is version stamped 0.18.5 but diverges substantially from upstream CAF 0.18.5 (the streaming subsystem is removed, among other changes), so it is not a drop-in for dev-libs/caf and blocks it. Built minimally as shared libraries -- only the core, io and net modules that Broker links -- so net-analyzer/zeek can unbundle its vendored copy and link this instead.

• dev-libs/zfp::guru - Ebuilds: 1, Testing: 1.0.1
  Description: zfp is a compressed format for representing multidimensional floating-point and integer arrays. zfp provides compressed-array classes that support high throughput read and write random access to individual array elements. zfp also supports serial and parallel (OpenMP and CUDA) compression of whole arrays, e.g., for applications that read and write large data sets to and from disk. zfp uses lossy but optionally error-bounded compression to achieve high compression ratios. Bit-for-bit lossless compression is also possible through one of zfp's compression modes. zfp works best for 2D, 3D, and 4D arrays that exhibit spatial correlation, such as continuous fields from physics simulations, natural images, regularly sampled terrain surfaces, etc. zfp compression of 1D arrays is possible but generally discouraged. zfp is freely available as open source and is distributed under a BSD license. zfp is primarily written in C and C++ but also includes Python and Fortran bindings. zfp conforms to various language standards, including C89, C99, C11, C++98, C++11, and C++14, and is supported on Linux, macOS, and Windows.
