Member Data Documentation

PP_Resource(* PPB_RemovableStorage_Dev_0_1::Create)(PP_Instance instance)

Creates a removable storage resource.

Parameters

[in] instance A PP_Instance identifying one instance of a module.

Returns: A PP_Resource corresponding to a removable storage resource if successful, 0 if failed.

int32_t(* PPB_RemovableStorage_Dev_0_1::EnumerateDevices)(PP_Resource removable_storage, struct PP_ArrayOutput output, struct PP_CompletionCallback callback)

Enumerates removable storage devices.

Parameters

[in]	removable_storage	A `PP_Resource` corresponding to a removable storage resource.
[in]	output	An output array which will receive `PPB_RemovableStorageDeviceRef` resources on success. Please note that the ref count of those resources has already been increased by 1 for the caller.
[in]	callback	A `PP_CompletionCallback` to run on completion.

PP_Bool(* PPB_RemovableStorage_Dev_0_1::IsRemovableStorage)(PP_Resource resource)

Determines if the given resource is a removable storage resource.

Parameters

[in] resource A PP_Resource containing a resource.

Returns: A PP_Bool containing PP_TRUE if the given resource is a removable storage resource, otherwise PP_FALSE.

int32_t(* PPB_RemovableStorage_Dev_0_1::MonitorDeviceChange)(PP_Resource removable_storage, PP_MonitorDeviceChangeCallback callback, void *user_data)

Requests device change notifications.

Parameters

[in]	removable_storage	A `PP_Resource` corresponding to a removable storage resource.
[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 `removable_storage` is 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`.

int32_t(* PPB_RemovableStorage_Dev_0_1::Open)(PP_Resource removable_storage, PP_Resource file_system, PP_Resource device_ref, struct PP_CompletionCallback callback)

Opens removable file system.

Parameters

[in]	removable_storage	A `PP_Resource` corresponding to a removable storage resource.
[in]	file_system	A `PP_Resource` corresponding to a file system of PP_FILESYSTEMTYPE_REMOVABLESTORAGE type.
[in]	device_ref	A `PP_Resource` corresponding to a device reference.
[in]	callback	A `PP_CompletionCallback` to run on completion.
