## Member Function Documentation

static RC osl::DirectoryItem::get | ( | const ::rtl::OUString & | ustrFileURL,
|  | DirectoryItem & | rItem
| ) |  |
| inline static

Retrieve a single directory item.

Retrieves a single directory item. The returned handle has an initial refcount of 1. Due to performance issues it is not recommended to use this function while enumerating the contents of a directory. In this case use osl_getNextDirectoryItem() instead.

Parameters

  ustrFileURL | [in] An absolute file URL.
  rItem | [out] On success it receives a handle which can be used for subsequent calls to osl_getFileStatus(). The handle has to be released by a call to osl_releaseDirectoryItem().

Returns
  E_None on success E_INVAL the format of the parameters was not valid E_NOMEM not enough memory for allocating structures E_ACCES permission denied E_MFILE too many open files used by the process E_NFILE too many open files in the system E_NOENT no such file or directory E_LOOP too many symbolic links encountered E_NAMETOOLONG the file name is too long E_NOTDIR a component of the path prefix of path is not a directory E_IO on I/O errors E_MULTIHOP multihop attempted E_NOLINK link has been severed E_FAULT bad address E_INTR the function call was interrupted

  Directory::getNextItem()

RC osl::DirectoryItem::getFileStatus | ( | FileStatus & | rStatus | ) |
| inline

Retrieve information about a single file or directory.

Parameters

  rStatus | [in|out] Reference to a class which receives the information of the file or directory represented by this directory item.

Returns
  E_None on success E_NOMEM not enough memory for allocating structures E_INVAL the format of the parameters was not valid E_LOOP too many symbolic links encountered E_ACCES permission denied E_NOENT no such file or directory E_NAMETOOLONG file name too long E_BADF invalid oslDirectoryItem parameter E_FAULT bad address E_OVERFLOW value too large for defined data type E_INTR function call was interrupted E_NOLINK link has been severed E_MULTIHOP components of path require hopping to multiple remote machines and the file system does not allow it E_MFILE too many open files used by the process E_NFILE too many open files in the system E_NOSPC no space left on device E_NXIO no such device or address E_IO on I/O errors E_NOSYS function not implemented

bool osl::DirectoryItem::is | ( |  | ) |
| inline

Check for validity of this instance.

Returns
  true if object is valid directory item else false.

bool osl::DirectoryItem::isIdenticalTo | ( | const DirectoryItem & | pOther | ) |
| inline

Determine if a directory item point the same underlying file.

The comparison is done first by URL, and then by resolving links to find the target, and finally by comparing inodes on unix.

Parameters

  [in] | pOther | A directory handle to compare with the underlying object's item

Returns
  true: if the items point to an identical resource
  false: if the items point to a different resource, or a fatal error occurred

Since
  LibreOffice 3.6

DirectoryItem& osl::DirectoryItem::operator= | ( | const DirectoryItem & | rItem | ) |
| inline

Assignment operator.
