- .TH INTRO 9
- .SH NAME
- 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.
- .PP
- The
- .SM SYNOPSIS
- subsections do not show the header files needed for
- the standard kernel declarations.
- The primary combinations summarised below:
- .IP
- .RS
- .ta \w'\fL#include 'u
- .nf
- .B
- #include "u.h"
- .B
- #include "../port/lib.h"
- .B
- #include "mem.h"
- .B
- #include "dat.h"
- .B
- #include "fns.h"
- .B
- #include "../port/error.h"
- .PP
- .I "furthermore, added in IP code:"
- .br
- .B
- #include "../ip/ip.h"
- .PP
- .I "furthermore, in hardware device drivers:"
- .br
- .B
- #include "io.h"
- .br
- .B
- #include "ureg.h"
- .PP
- .I "furthermore, in network interfaces or ether drivers:"
- .B
- #include "../port/netif.h"
- .fi
- .RE
- .PP
- 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.
