The following table from the C Standard, subclause 7.1.2 [ISO/IEC 9899:2011], lists these standard headers:
<assert.h> | <float.h> | <math.h> | <stdatomic.h> | <stdlib.h> | <time.h> |
<complex.h> | <inttypes.h> | <setjmp.h> | <stdbool.h> | <stdnoreturn.h> | <uchar.h> |
<ctype.h> | <iso646.h> | <signal.h> | <stddef.h> | <string.h> | <wchar.h> |
<errno.h> | <limits.h> | <stdalign.h> | <stdint.h> | <tgmath.h> | <wctype.h> |
<fenv.h> | <locale.h> | <stdarg.h> | <stdio.h> | <threads.h> |
Do not reuse standard header file names, system-specific header file names, or other header file names.
...
Using header file names that conflict with other header file names can result in an incorrect file being included.
