Directive Statements
Directive statements provide direction to the GateD configuration
language parser about included files and the directories in which
these files reside. Directive statements are immediately acted upon
by the parser. Other statements terminate with a semi-colon (;), but
directive statements terminate with a newline. The two directive
statements are:
- %directory "directory"
- Defines the directory where the include files are stored. When
it is used, GateD looks in the directory identified by pathname
for any included files that do not have a fully qualified
filename i.e. do not begin with "/". This statement does not
actually change the current the directory, it just specifies the
prefix applied to included file names.
- %include "filename"
- Identifies an include file. The contents of the file is
included in the gated.conf file at the point in the
gated.conf file where the
%include directive is
encountered. If the filename is not fully qualified, i.e. does
not begin with "/", it is considered to be relative to the
directory defined in the %directory directive. The
%include directive statement causes the specified
file to be parsed completely before resuming with this file.
Nesting up to ten levels is supported. The maximum nesting level
may be increased by changing the definition of
FI_MAX in parse.h.
In a complex environment, segmenting a large configuration into smaller
more easily understood segments might be helpful, but one of the great
advantages of GateD is that it combines the configuration of several
different routing protocols into a single file. Segmenting a small file
unnecessarily complicates routing configurations.
