Member Data Documentation

PP_Resource(* PPB_FileSystem_1_0::Create)(PP_Instance instance, PP_FileSystemType type)

Create() creates a file system object of the given type.

Parameters

[in]	instance	A `PP_Instance` identifying the instance with the file.
[in]	type	A file system type as defined by `PP_FileSystemType` enum (except PP_FILESYSTEMTYPE_ISOLATED, which is currently not supported).

Definition at line 47 of file ppb_file_system.h.

PP_FileSystemType(* PPB_FileSystem_1_0::GetType)(PP_Resource file_system)

GetType() returns the type of the provided file system.

Parameters

[in] file_system A PP_Resource corresponding to a file system.

Returns: A PP_FileSystemType with the file system type if valid or PP_FILESYSTEMTYPE_INVALID if the provided resource is not a valid file system. It is valid to call this function even before Open() completes.

Definition at line 92 of file ppb_file_system.h.

PP_Bool(* PPB_FileSystem_1_0::IsFileSystem)(PP_Resource resource)

IsFileSystem() determines if the provided resource is a file system.

Parameters

[in] resource A PP_Resource corresponding to a file system.

Returns: PP_TRUE if the resource is a PPB_FileSystem, PP_FALSE if the resource is invalid or some type other than PPB_FileSystem.

Definition at line 58 of file ppb_file_system.h.

int32_t(* PPB_FileSystem_1_0::Open)(PP_Resource file_system, int64_t expected_size, struct PP_CompletionCallback callback)

Open() opens the file system. A file system must be opened before running any other operation on it.

Parameters

[in]	file_system	A `PP_Resource` corresponding to a file system.
[in]	expected_size	The expected size of the file system. Note that this does not request quota; to do that, you must either invoke requestQuota from JavaScript: http://www.html5rocks.com/en/tutorials/file/filesystem/#toc-requesting-quota or set the unlimitedStorage permission for Chrome Web Store apps: http://code.google.com/chrome/extensions/manifest.html#permissions
[in]	callback	A `PP_CompletionCallback` to be called upon completion of Open().
