The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3]
[12] char16_t [13] Part of the C standard since C11, [14] in <uchar.h>, a type capable of holding 16 bits even if wchar_t is another size. If the macro __STDC_UTF_16__ is defined as 1, the type is used for UTF-16 on that system. This is always the case in C23. [15] C++ does not define such a macro, but the type is always used for UTF-16 in that ...
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.

The C POSIX library is a specification of a C standard library for POSIX systems. It was developed at the same time as the ANSI C standard. Some effort was made to make POSIX compatible with standard C ; POSIX includes additional functions to those introduced in standard C.
They are implemented as a group of macro constants in the C standard library in the iso646.h header. The tokens were created by Bjarne Stroustrup for the pre-standard C++ language [1] and were added to the C standard in a 1995 amendment to the C90 standard via library to avoid the breakage of existing code.
stdarg.h is a header in the C standard library of the C programming language that allows functions to accept an indefinite number of arguments. [1] It provides facilities for stepping through a list of function arguments of unknown number and type. C++ provides this functionality in the header cstdarg.
In the C and C++ programming languages, a header file is a file whose text is included in another source file by the compiler, usually by the use of compiler directives at the beginning of the source file. A prefix header differs from a normal header file in that it is automatically included at the beginning of every source file by the compiler ...
