Constructor & Destructor Documentation

pp::RemovableStorage_Dev::RemovableStorage_Dev ( const InstanceHandle &  instance )

explicit

Creates a removable storage resource.

Parameters

[in]

instance

A InstanceHandle identifying one instance of a module.

Returns

A Resource corresponding to a removable storage resource if successful, 0 if failed.

Definition at line 38 of file removable_storage_dev.cc.

Member Function Documentation

int32_t pp::RemovableStorage_Dev::EnumerateDevices

(

const CompletionCallbackWithOutput< std::vector< DeviceRef_Dev > > &

callback

)

Enumerates removable storage devices.

Parameters

[in]

callback

A CompletionCallbackWithOutput to run on completion.

Returns

An error code from pp_errors.h.

Definition at line 56 of file removable_storage_dev.cc.

References pp::Resource::pp_resource().

bool pp::RemovableStorage_Dev::IsAvailable ( )

static

Determines if the given resource is available.

Returns

A bool containing true if the given resource is available, otherwise false.

Definition at line 51 of file removable_storage_dev.cc.

bool pp::RemovableStorage_Dev::IsRemovableStorage

(

)

Determines if the given resource is a removable storage resource.

Returns

A bool containing true if the given resource is a removable storage resource, otherwise false.

Definition at line 46 of file removable_storage_dev.cc.

References pp::Resource::pp_resource().

int32_t pp::RemovableStorage_Dev::MonitorDeviceChange	(	PP_MonitorDeviceChangeCallback	callback,
		void *	user_data
	)

Requests device change notifications.

Parameters

[in]	callback	The callback to receive notifications. If not NULL, it will be called once for the currently available devices, and then every time the list of available devices changes. All calls will happen on the same thread as the one on which MonitorDeviceChange() is called. It will receive notifications until it will be destroyed or MonitorDeviceChange() is called to set a new callback for removable_storage. You can pass NULL to cancel sending notifications.
[in,out]	user_data	An opaque pointer that will be passed to callback.

Returns

An error code from pp_errors.h.

Definition at line 69 of file removable_storage_dev.cc.

References pp::Resource::pp_resource().

int32_t pp::RemovableStorage_Dev::Open	(	const FileSystem &	file_system,
		const DeviceRef_Dev &	device_ref,
		const CompletionCallback &	callback
	)

Opens removable file system.

Parameters

[in]	file_system	A FileSystem corresponding to a file system of PP_FILESYSTEMTYPE_REMOVABLESTORAGE type.
[in]	device_ref	A DeviceRef_Dev corresponding to a device reference.
[in]	callback	A CompletionCallback to run on completion.

Returns

An error code from pp_errors.h.
