intro \- introduction to kernel functions
|

.SH DESCRIPTION
|
||
|
|
This section of the manual
|
||
|
|
describes the functions publicly available to the authors of
|
||
|
|
kernel code, particularly device drivers (real and virtual).
|
||
|
|
This section will eventually be much expanded, but this makes a start.

The

|
|
.SM SYNOPSIS
|
||
|
|
subsections do not show the header files needed for
|
||
|
|
the standard kernel declarations.

|

There might also be specific include files needed by
|
||
|
|
drivers on particular platforms or to use specialised kernel interfaces.
|
||
|
|
The easiest method is to check the source of likely-looking drivers nearby.
