On Mac and iOS the C Standard Library implementation is part of libSystem, a core library located in /usr/lib/libSystem.dylib. In general all commonly available linux distributions will use libstdc++ by default. It is an ongoing project to implement the Standard C++ library on GNU/Linux. On the other hand, the implementation of the C++ Standard Library takes place in libstdc++ or The GNU Standard C++ Library. The version number got incremented to 6 in order to avoid any confusion with the previous Linux libc versions (they couldn't name it glibc.so.6: all Linux libraries must start with the lib prefix). So don't worry if you find a file in your disk named libc.so.6: it's the modern glibc. For a while, Linux libc was the standard C library in many Linux distributions.Īfter years of development, glibc turned out to be way superior to Linux libc and all Linux distributions that had been using it switched back to glibc. However, during the ‘90s there was for a while a glibc competitor called Linux libc (or just libc), born from a fork of glibc 1.x. Not all standard C functions are found in glibc: most mathematical functions are actually implemented in libm, a separate library.Īs of today glibc is the most widely used C library on Linux. The GNU C Library, also known as glibc, is the GNU Project's implementation of the C Standard Library. Sometimes it's a core part of the system, sometimes it comes as an additional component - the compiler - that must be downloaded separately. , through the so-called system calls), so each platform has its own Standard Library implementation. They have to rely upon the functionalities provided by their operating system (read/write files, allocate memory, create threads.

Developers who work on the Standard Library implementation read the official ISO requirements and translate them into code. Implementing the C and C++ Standard Library The C++ Standard Library incorporates the C Standard Library too and it is specified in the C++ standard (e.g. The C++ Standard Library is a set of C++ template classes which provides common programming data structures and functions such as lists, stacks, arrays, algorithms, iterators and any other C++ component you can think of. The same C Standard Library concept, but specific for C++. The content is spread across different headers, like math.h I've mentioned above. The C Standard Library, also known as ISO C Library is a collection of macros, types and functions for tasks such as input/output processing, string handling, memory management, mathematical computations and many other operating system services. This is what people working on compilers and implementations do: the former crafts a tool that can read and process C and C++ source files, the latter turns the Standard Library into code. Someone has to read the standard and transform it into something a computer can digest.

Definition of min function from the math.h header.Īs you can see, almost no code is involved. It is called the Standard Library.įor example, here is a selection from the first part of a C standard where the anatomy of the main function is defined:Ģ.

I have been playing around with C++ for a while and one thing that always got me confused in the beginning was its anatomy: where do the core functions and classes I'm using come from? Who invented them? Are they packaged somewhere in my system? Is there a kind of official C++ manual around?
