| modernize-deprecated-headers |
| ============================ |
| |
| Some headers from C library were deprecated in C++ and are no longer welcome in |
| C++ codebases. Some have no effect in C++. For more details refer to the C++ 14 |
| Standard [depr.c.headers] section. |
| |
| This check replaces C standard library headers with their C++ alternatives and |
| removes redundant ones. |
| |
| Important note: the Standard doesn't guarantee that the C++ headers declare all |
| the same functions in the global namespace. The check in its current form can |
| break the code that uses library symbols from the global namespace. |
| |
| * `<assert.h>` |
| * `<complex.h>` |
| * `<ctype.h>` |
| * `<errno.h>` |
| * `<fenv.h>` // deprecated since C++11 |
| * `<float.h>` |
| * `<inttypes.h>` |
| * `<limits.h>` |
| * `<locale.h>` |
| * `<math.h>` |
| * `<setjmp.h>` |
| * `<signal.h>` |
| * `<stdarg.h>` |
| * `<stddef.h>` |
| * `<stdint.h>` |
| * `<stdio.h>` |
| * `<stdlib.h>` |
| * `<string.h>` |
| * `<tgmath.h>` // deprecated since C++11 |
| * `<time.h>` |
| * `<uchar.h>` // deprecated since C++11 |
| * `<wchar.h>` |
| * `<wctype.h>` |
| |
| If the specified standard is older than C++11 the check will only replace |
| headers deprecated before C++11, otherwise -- every header that appeared in |
| the previous list. |
| |
| These headers don't have effect in C++: |
| |
| * `<iso646.h>` |
| * `<stdalign.h>` |
| * `<stdbool.h>` |
