SYNOPSIS

9         use Glib;
10         use Glib::IO;
11
12         # Synchronous I/O
13         $cur_dir = Glib::IO::File::new_for_path('.');
14         $enumerator = $cur_dir->enumerate_children('standard::*', [], undef);
15         while ($file_info = $enumerator->next_file(undef)) {
16             say 'Path: ' + $file_info->get_name();
17         }
18
19         # Asynchronous I/O
20         $loop = Glib::MainLoop->new();
21         $file = Glib::IO::File::new_for_path('/etc/passwd');
22         $file->query_info_async('access::can-read,access::can-write', [], 0, sub {
23             my ($file, $res, $data) = @_;
24             my $info = $file->query_info_finish();
25             say 'Can read:  ' + $info->get_attribute_boolean('access::can-read');
26             say 'Can write: ' + $info->get_attribute_boolean('access::can-write');
27             $loop->quit();

ABSTRACT

36       Perl bindings to the GIO library. This modules allows you to write
37       portable code to perform synchronous and asynchronous I/O; implement
38       IPC clients and servers using the DBus specification; interact with the
39       operating system and platform using various services.

DESCRIPTION

42       The "Glib::IO" module allows a Perl developer to access the GIO
43       library, the high level I/O and platform library of the GNOME
44       development platform. GIO is used for:
45
46       •   local and remote enumeration and access of files
47
48           GIO has multiple backends to access local file systems; SMB/CIFS
49           volumes; WebDAV resources; compressed archives; local devices and
50           remote web services.
51
52       •   stream based I/O
53
54           Including files, memory buffers, and network streams.
55
56       •   low level and high level network operations
57
58           Sockets, Internet addresses, datagram-based connections, and TCP
59           connections.
60
61       •   TLS/SSL support for socket connections
62
63       •   DNS resolution and proxy
64
65       •   low level and high level DBus classes
66
67           GIO allows the implementation of clients and servers, as well as
68           proxying objects over DBus connections.
69
70       Additionally, GIO has a collection of high level classes for writing
71       applications that integrate with the platform, like:
72
73       settings
74       network monitoring
75       a base Application class
76       extensible data models
77       content type matching
78       application information and launch
79
80       For more information, please visit the GIO reference manual available
81       on <https://developer.gnome.org/gio/stable>. The Perl API closely
82       matches the C one, and eventual deviations will be documented here.
83
84       The principles underlying the mapping from C to Perl are explained in
85       the documentation of Glib::Object::Introspection, on which "Glib::IO"
86       is based.
87
88       Glib::Object::Introspection also comes with the "perli11ndoc" program
89       which displays the API reference documentation of all installed
90       libraries organized in accordance with these principles.
