| // This file is included by <cstdio> and the like that are used from other |
| // libc++ headers that are wrapped by ktl. This file exists to preempt those |
| // inclusions so that libc++'s <wchar.h> wrapper header won't be used, since |
| // it's not compatible with the kernel environment. However, other libc++ |
| // headers also use `#include_next <wchar.h>` to get to "the system libc" |
| // version of the header. To satisfy those, include-after/wchar.h provides the |
| // actual declarations needed from the standard C <wchar.h> API. So this |
| // header just defers to that one, but must exist separately in this directory |
| // so that it preempt's libc++'s wrapper. This can't itself use #include_next |
| // because that would reach libc++'s wrapper before the include-after file. |
