## Description

These functions are useful for dealing with lists of modules, and performing operations on all of them.

`cancellable` : | optional cancellation object. [allow-none]
`error` : | location to place an error on failure. [allow-none]
Returns : | A newly allocated list of GckModule objects, which should be released with `gck_list_unref_free()`.

Setup an enumerator for listing matching objects on the modules.

This call will not block but will return an enumerator immediately.

`modules` : | The modules
`attrs` : | Attributes that the objects must have, or empty for all objects
`session_options` : | Options from GckSessionOptions
Returns : | A new enumerator, which should be released with `g_object_unref()`.

### gck_modules_enumerate_uri ()

    GckEnumerator *     gck_modules_enumerate_uri           (GList *modules,
                                                             const gchar *uri,

Enumerate objects that match a URI.

This call will not block. Use the GckEnumerator functions in order to get at the actual objects that match.

`modules` : | The modules
`uri` : | The URI that the enumerator will match
`session_options` : | Options from GckSessionOptions
`error` : | A location to raise an error on failure.
Returns : | A new GckEnumerator, or `NULL` if an error occurs.

### gck_modules_get_slots ()

    GList *             gck_modules_get_slots               (GList *modules,
                                                             gboolean token_present);

Get a list of slots for across all of the modules.

`modules` : | The modules
`token_present` : | Whether to only list slots with token present
Returns : | A list of GckSlot objects, which should be freed with `gck_list_unref_free()`.

### gck_modules_object_for_uri ()

    GckObject *         gck_modules_object_for_uri          (GList *modules,
                                                             const gchar *uri,

Find an object that matches a URI.

This call can block. Use `gck_modules_enumerate_uri()` for a non-blocking version.

`modules` : | The modules
`uri` : | The URI the objects must match
`session_options` : | Options from GckSessionOptions
`error` : | A location to raise an error on failure.
Returns : | A new GckObject which should be released with `g_object_unref()`, or `NULL` if no matching object was found.

Find objects that match a URI.

This call can block. Use `gck_modules_enumerate_uri()` for a non-blocking version.

`modules` : | The modules
`uri` : | The URI the objects must match
`session_options` : | Options from GckSessionOptions
`error` : | A location to raise an error on failure.

### gck_modules_token_for_uri ()

    GckSlot *           gck_modules_token_for_uri           (GList *modules,
                                                             const gchar *uri,
                                                             GError **error);

Lookup a token that matches the URI.

`modules` : | The modules
`uri` : | The URI that the token must match
`error` : | A location to raise an error on failure
Returns : | A newly allocated GckSlot or `NULL` if no such token was found.

### gck_modules_tokens_for_uri ()

    GList *             gck_modules_tokens_for_uri          (GList *modules,
                                                             const gchar *uri,
                                                             GError **error);

Lookup a token that matches the URI.

`modules` : | The modules
`uri` : | The URI that the token must match
`error` : | A location to raise an error on failure
Returns : | A list of newly allocated GckSlot objects. Use `gck_list_unref_free()` to release the list once you're done with it. [transfer full]
