Note that new library files have been introduced in the
new C9X (read draft)
standard, some of the library files above have been slightly
modified, these changes will be included here when they
become familliar enough.
There are many more very widely used libraries that are
non-standard. E.g. <conio.h> or <windows.h>
- these too will be included in this section soon.
