# Description:

# This simple script shows how to modify the content of a feature manager

# data file.

# 

#

use strict;

use FMCreate;

#

# Hardwire the datafile - this is only an example.

# 

my $datfile = "features.dat";

my $datfile2 = "features2.dat";

my $datfile3 = "features3.dat";

#

# Create an object that represents a feature data file.

#

my $fmc = FMCreate->new();

#

# Load the content of the data file into our FMCreate object.

# Note that this will die if the content does not seem to be a feature set

# file. This can happen if the first four bytes aren't 'feat' or if reading

# the file fails at any point. This will also happen if the file is the wrong

# size.

#

$fmc->LoadUp($datfile) or die "Failed to load up data from '$datfile'\n";

#

# Get feature flag '0x10000009'

#

my $ffuid = 0x10000009;

my $ff = $fmc->GetFeatureFlagByUID($ffuid);

if(ref($ff) ne "FeatureFlag")

{

	printf "Couldn't get feature flag uid 0x%0x from file $datfile\n";

	die "no feature flag";

}

#

# Change the feature flag.. Note that the feature flag object '$ff' is a

# reference to the feature flag in '$fmc' - it's still in there, so when

# we modify it here it will affect what '$fmc' will write.

#

$ff->BlackListed(1);

$fmc->WriteToFile($datfile2) or die "Couldn't write feature data file '$datfile2'\n";

#

# Now add a new feature. The three arguments are UID, status flags (not defined

# here) and user data word.

#

my $newfeat = FeatureFlag->new(0x12345678, undef, 0xabcd);

die "Couldn't create new feature flag object.\n" unless(ref($newfeat));

#

# Add it to our existing feature data.

#

$fmc->AddFeatureFlag($newfeat) or die "Couldn't add new feature flag..\n";

#

# Remove the original feature flag.

#

$fmc->RemoveFeatureFlagByUID($ffuid) or die "Couldn't remove feature flag\n";

$fmc->WriteToFile($datfile3);
