=head1 NAME
Dahdi - Perl interface to Dahdi information
This package allows access from Perl to information about Dahdi
hardware and loaded Dahdi devices.
=head1 SYNOPSIS
# Listing channels in analog spans:
use Dahdi;
# scans system:
my @spans = Dahdi::spans();
for my $span (@spans) {
next if ($span->is_digital);
$span->num. " - [". $span->type ."] ". $span->name. "\n";
for my $chan ($span->chans) {
print " - ".$chan->num . " - [". $chan->type. "] ". $chan->fqn". \n";
}
}
=cut
our $virt_base;
our $proc_dahdi_base;
our $proc_xpp_base;
our $proc_usb_base;
our $sys_base;
=head1 spans()
Returns a list of span objects, ordered by span number.
=cut
sub spans() {
my @spans;
-d $proc_dahdi_base or return ();
foreach my $zfile (glob "$proc_dahdi_base/*") {
next unless ($zfile =~ m{^$proc_dahdi_base/\d+$});
my $span = Dahdi::Span->new($zfile);
push(@spans, $span);
}
@spans = sort { $a->num <=> $b->num } @spans;
return @spans;
}
=head1 ENVIRONMENT
If C<DAHDI_VIRT_TOP> is set in the environment, it will be considered
as a path to a directory that holds a dump (copy) of all the required
files from /proc and /sys . You can generate that directory using the
script C<build_tools/dump_sys_state> .
=head1 SEE ALSO
Span objects: L<Dahdi::Span>.
Dahdi channels objects: L<Dahdi::Chan>.
Dahdi hardware devices information: L<Dahdi::Hardware>.
Xorcom Astribank -specific information: L<Dahdi::Xpp>.
