The C standard library or libc is the standard library for the C programming language, as specified in the ISO C standard. [ 1 ] Starting from the original ANSI C standard, it was developed at the same time as the C library POSIX specification, which is a superset of it. [ 2 ][ 3 ] Since ANSI C was adopted by the International Organization for ...
The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
This header is part of neither ISO C nor POSIX. The file, as defined in the second version of the Single UNIX Specification, simply contains all of the functionality of C89 stdarg.h, with the exceptions that: it cannot be used in standard C new-style definitions; the given argument may be omitted (standard C requires at least one argument)

C11 (previously C1X, formally ISO/IEC 9899:2011), [1] is a past standard for the C programming language. It replaced C99 (standard ISO/IEC 9899:1999) and has been superseded by C17 (standard ISO/IEC 9899:2018). C11 mainly standardizes features already supported by common contemporary compilers, and includes a detailed memory model to better ...
windows.h. windows.h is a Windows -specific header file for the C and C++ programming languages which contains declarations for all of the functions in the Windows API, all the common macros used by Windows programmers, and all the data types used by the various functions and subsystems. It defines a very large number of Windows specific ...
Overview. The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
unistd.h. In the C and C++ programming languages, unistd.h is the name of the header file that provides access to the POSIX operating system API. [ 1 ] It is defined by the POSIX.1 standard, the base of the Single Unix Specification, and should therefore be available in any POSIX-compliant operating system and compiler.
