Name	From	Description
<assert.h>		Contains the assert macro, used to assist with detecting logical errors and other types of bug in debugging versions of a program.
<complex.h>	C99	A set of functions for manipulating complex numbers.
<ctype.h>		Defines set of functions used to classify characters by their types or to convert between upper and lower case in a way that is independent of the used character set (typically ASCII or one of its extensions, although implementations utilizing EBCDIC are also known).
<errno.h>		For testing error codes reported by library functions.
<fenv.h>	C99	Defines a set of functions for controlling floating-point environment.
<float.h>		Defines macro constants specifying the implementation-specific properties of the floating-point library.
<inttypes.h>	C99	Defines exact width integer types.
<iso646.h>	NA1	Defines several macros that implement alternative ways to express several standard tokens. For programming in ISO 646 variant character sets.
<limits.h>		Defines macro constants specifying the implementation-specific properties of the integer types.
<locale.h>		Defines localization functions.
<math.h>		Defines common mathematical functions.
<setjmp.h>		Declares the macros setjmp and longjmp, which are used for non-local exits.
<signal.h>		Defines signal handling functions.
<stdalign.h>	C11	For querying and specifying the alignment of objects.
<stdarg.h>		For accessing a varying number of arguments passed to functions.
<stdatomic.h>	C11	For atomic operations on data shared between threads.
<stdbool.h>	C99	Defines a boolean data type.
<stddef.h>		Defines several useful types and macros.
<stdint.h>	C99	Defines exact width integer types.
<stdio.h>		Defines core input and output functions
<stdlib.h>		Defines numeric conversion functions, pseudo-random numbers generation functions, memory allocation, process control functions
<stdnoreturn.h>	C11	For specifying non-returning functions.
<string.h>		Defines string handling functions.
<tgmath.h>	C99	Defines type-generic mathematical functions.
<threads.h>	C11	Defines functions for managing multiple Threads as well as mutexes and condition variables.
<time.h>		Defines date and time handling functions
<uchar.h>	C11	Types and functions for manipulating Unicode characters.
<wchar.h>	NA1	Defines wide string handling functions.
<wctype.h>	NA1	Defines set of functions used to classify wide characters by their types or to convert between upper and lower case
