Core API Documentation
|
|
|
|
|
======================
|
|
|
|
|
|
|
|
|
|
This is the beginning of a manual for core kernel APIs. The conversion
|
|
|
|
|
(and writing!) of documents for this manual is much appreciated!

Core utilities
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
This section has general and "core core" documentation. The first is a
|
|
|
|
|
massive grab-bag of kerneldoc info left over from the docbook days; it
|
|
|
|
|
should really be broken up someday when somebody finds the energy to do
|
|
|
|
|
it.
