GFile is a high level abstraction for manipulating files on a
virtual file system. GFiles are lightweight, immutable
objects that do no I/O upon creation. It is necessary to understand that
GFile objects do not represent files, merely an identifier for a file. All
file content I/O is implemented as streaming operations (see GInputStream and
GOutputStream). To construct a GFile, you can use:
gFileNewForPath if you have a path.
gFileNewForUri if you have a URI.
gFileNewForCommandlineArg for a command line argument.
gFileParseName from a utf8 string gotten from gFileGetParseName. One way to think of a GFile is as an abstraction of a pathname. For normal
files the system pathname is what is stored internally, but as GFiles
are extensible it could also be something else that corresponds to a pathname
in a userspace implementation of a filesystem.
GFiles make up hierarchies of directories and files that correspond to the
files on a filesystem. You can move through the file system with GFile using
gFileGetParent to get an identifier for the parent directory, gFileGetChild
to get a child within a directory, gFileResolveRelativePath to resolve a relative
path between two GFiles. There can be multiple hierarchies, so you may not
end up at the same root if you repeatedly call gFileGetParent on two different
files. All GFiles have a basename (get with gFileGetBasename). These names
are byte strings that are used to identify the file on the filesystem (relative to
its parent directory) and there is no guarantees that they have any particular charset
encoding or even make any sense at all. If you want to use filenames in a user
interface you should use the display name that you can get by requesting the
G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with gFileQueryInfo.
This is guaranteed to be in utf8 and can be used in a user interface. But always
store the real basename or the GFile to use to actually access the file, because
there is no way to go from a display name to the actual name. Using GFile as an identifier has the same weaknesses as using a path in that
there may be multiple aliases for the same file. For instance, hard or
soft links may cause two different GFiles to refer to the same file.
Other possible causes for aliases are: case insensitive filesystems, short
and long names on Fat/NTFS, or bind mounts in Linux. If you want to check if
two GFiles point to the same file you can query for the
G_FILE_ATTRIBUTE_ID_FILE attribute. Note that GFile does some trivial
canonicalization of pathnames passed in, so that trivial differences in the
path string used at creation (duplicated slashes, slash at end of path, "."
or ".." path segments, etc) does not create different GFiles. Many GFile operations have both synchronous and asynchronous versions
to suit your application. Asynchronous versions of synchronous functions
simply have async() appended to their function names. The asynchronous
I/O functions call a GAsyncReadyCallback which is then used to finalize
the operation, producing a GAsyncResult which is then passed to the
function's matching finish() operation. Some GFile operations do not have synchronous analogs, as they may
take a very long time to finish, and blocking may leave an application
unusable. Notable cases include:
gFileMountMountable to mount a mountable file.
gFileUnmountMountableWithOperation to unmount a mountable file.
gFileEjectMountableWithOperation to eject a mountable file. One notable feature of GFiles are entity tags, or "etags" for
short. Entity tags are somewhat like a more abstract version of the
traditional mtime, and can be used to quickly determine if the file has
been modified from the version on the file system. See the HTTP 1.1
specification (http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html)
for HTTP Etag headers, which are a very similar concept.GFileQueryInfoFlagsGFileInfo. nefollow-symlinksGFileCreateFlagsnoneprivateGFileCopyFlagsnoneoverwritebackupnofollow-symlinksall-metadataGFileInfo).no-fallback-for-moveGFileMonitorFlagsGFileMonitor will watch for. nonewatch-mountsGFileProgressCallback(current.num.bytes, total.num.bytes, user.data)current.num.bytestotal.num.bytesuser.dataGFileReadMoreCallback(file.contents, file.size, callback.data)gFileLoadPartialContentsAsync(),
it may become necessary to determine if any more data from the file should be loaded.
A GFileReadMoreCallback function facilitates this by returning TRUE if more data
should be read, or FALSE otherwise. file.contentsfile.sizecallback.dataTRUE if more data should be read back. FALSE otherwise.
