g_io_module_new ()

GIOModule *
g_io_module_new (const gchar *filename);

Creates a new GIOModule that will load the specific shared library when in use.

g_io_module_scope_block ()

void
g_io_module_scope_block (GIOModuleScope *scope,
                         const gchar *basename);

Block modules with the given basename from being loaded when this scope is used with g_io_modules_scan_all_in_directory_with_scope() or g_io_modules_load_all_in_directory_with_scope().

Since: 2.30

g_io_module_scope_free ()

void
g_io_module_scope_free (GIOModuleScope *scope);

Free a module scope.

Since: 2.30

g_io_module_scope_new ()

GIOModuleScope *
g_io_module_scope_new (GIOModuleScopeFlags flags);

Create a new scope for loading of IO modules. A scope can be used for blocking duplicate modules, or blocking a module you don't want to load.

Specify the G_IO_MODULE_SCOPE_BLOCK_DUPLICATES flag to block modules which have the same base name as a module that has already been seen in this scope.

Since: 2.30

g_io_modules_load_all_in_directory ()

GList *
g_io_modules_load_all_in_directory (const gchar *dirname);

Loads all the modules in the specified directory.

If don't require all modules to be initialized (and thus registering all gtypes) then you can use g_io_modules_scan_all_in_directory() which allows delayed/lazy loading of modules.

g_io_modules_load_all_in_directory_with_scope ()

GList *
g_io_modules_load_all_in_directory_with_scope
                               (const gchar *dirname,
                                GIOModuleScope *scope);

Loads all the modules in the specified directory.

If don't require all modules to be initialized (and thus registering all gtypes) then you can use g_io_modules_scan_all_in_directory() which allows delayed/lazy loading of modules.

Since: 2.30

g_io_modules_scan_all_in_directory ()

void
g_io_modules_scan_all_in_directory (const char *dirname);

Scans all the modules in the specified directory, ensuring that any extension point implemented by a module is registered.

This may not actually load and initialize all the types in each module, some modules may be lazily loaded and initialized when an extension point it implementes is used with e.g. g_io_extension_point_get_extensions() or g_io_extension_point_get_extension_by_name().

If you need to guarantee that all types are loaded in all the modules, use g_io_modules_load_all_in_directory().

Since: 2.24

g_io_modules_scan_all_in_directory_with_scope ()

void
g_io_modules_scan_all_in_directory_with_scope
                               (const gchar *dirname,
                                GIOModuleScope *scope);

Scans all the modules in the specified directory, ensuring that any extension point implemented by a module is registered.

This may not actually load and initialize all the types in each module, some modules may be lazily loaded and initialized when an extension point it implementes is used with e.g. g_io_extension_point_get_extensions() or g_io_extension_point_get_extension_by_name().

If you need to guarantee that all types are loaded in all the modules, use g_io_modules_load_all_in_directory().

g_io_module_load ()

void
g_io_module_load (GIOModule *module);

Required API for GIO modules to implement.

This function is run after the module has been loaded into GIO, to initialize the module. Typically, this function will call g_io_extension_point_implement().

g_io_module_unload ()

void
g_io_module_unload (GIOModule *module);

Required API for GIO modules to implement.

This function is run when the module is being unloaded from GIO, to finalize the module.

g_io_module_query ()

char **
g_io_module_query (void);

Optional API for GIO modules to implement.

Should return a list of all the extension points that may be implemented in this module.

This method will not be called in normal use, however it may be called when probing existing modules and recording which extension points that this model is used for. This means we won't have to load and initialize this module unless its needed.

If this function is not implemented by the module the module will always be loaded, initialized and then unloaded on application startup so that it can register its extension points during init.

Note that a module need not actually implement all the extension points that g_io_module_query() returns, since the exact list of extension may depend on runtime issues. However all extension points actually implemented must be returned by g_io_module_query() (if defined).

When installing a module that implements g_io_module_query() you must run gio-querymodules in order to build the cache files required for lazy loading.

GIOModule

typedef struct _GIOModule GIOModule;

Opaque module base class for extending GIO.

GIOModuleScope

typedef struct _GIOModuleScope GIOModuleScope;

Represents a scope for loading IO modules. A scope can be used for blocking duplicate modules, or blocking a module you don't want to load.

The scope can be used with g_io_modules_load_all_in_directory_with_scope() or g_io_modules_scan_all_in_directory_with_scope().

Since: 2.30

enum GIOModuleScopeFlags

Flags for use with g_io_module_scope_new().
