.Sh NAME
.Nm bsd.snmpmod.mk
.Sh SYNOPSIS
.Fd .include <bsd.snmpmod.mk>
.Sh DESCRIPTION
The file
.In bsd.snmpmod.mk
simplifies the building of modules for the Begemot SNMP daemon
.Xr bsnmpd 1 .
It provides some common functions for building a module and
relies on
.In bsd.lib.mk ,
which is included by
.In bsd.snmpmod.mk
to actually build the shared library.
.Pp
The following
.Xr make 1
variables control the special functions:
.Bl -tag -width ".Va EXTRAMIBDEFS"
.It Va MOD
The short name of the module.
The name of the shared library will be
.Pa snmp_${MOD}.so .
There must exist a file
.Pa ${MOD}_tree.def
for compilation with
.Xr gensnmptree 1
which contains the definition of the MIB tree implemented by the module.
.It Va EXTRAMIBDEFS
A list of extra MIB definition files for
.Xr gensnmptree 1 .
This is optional.
.It Va XSYM
A list of symbols to be extracted from the MIB definition files by
.Xr gensnmptree 1 .
This is optional.
.It Va DEFS
A list of MIB definition files to be installed.
This is optional.
.It Va BMIBS
A list of textual MIBs to be installed.
This is optional.
.El
.Pp
Three file are automatically created from the MIB definition files and
the
.Va XSYM
variable:
.Bl -tag -width ".Va EXTRAMIBDEFS"
.It Pa ${MOD}_tree.c
This contains a table with the tree implemented by the module.
It is automatically included into the
.Va SRCS
variable.
.It Pa ${MOD}_tree.h
This contains preprocessor defines for all the OIDs defined by the module
and can be included in the module's source code.
.It Pa ${MOD}_oid.h
OID preprocessor definitions for all the symbols listed in
.Va XSYMS .
This is to be included into the module's source code.
