Virtual Method

GioFilecopy

Declaration [src]

gboolean
copy (
  GFile* source,
  GFile* destination,
  GFileCopyFlags flags,
  GCancellable* cancellable,
  GFileProgressCallback progress_callback,
  gpointer progress_callback_data,
  GError** error
)

Description [src]

Copies the file source to the location specified by destination. Can not handle recursive copies of directories.

If the flag G_FILE_COPY_OVERWRITE is specified an already existing destination file is overwritten.

If the flag G_FILE_COPY_NOFOLLOW_SYMLINKS is specified then symlinks will be copied as symlinks, otherwise the target of the source symlink will be copied.

If the flag G_FILE_COPY_ALL_METADATA is specified then all the metadata that is possible to copy is copied, not just the default subset (which, for instance, does not include the owner, see GFileInfo).

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

If progress_callback is not NULL, then the operation can be monitored by setting this to a GFileProgressCallback function. progress_callback_data will be passed to this function. It is guaranteed that this callback will be called after all data has been transferred with the total number of bytes copied during the operation.

If the source file does not exist, then the G_IO_ERROR_NOT_FOUND error is returned, independent on the status of the destination.

If G_FILE_COPY_OVERWRITE is not specified and the target exists, then the error G_IO_ERROR_EXISTS is returned.

If trying to overwrite a file over a directory, the G_IO_ERROR_IS_DIRECTORY error is returned. If trying to overwrite a directory with a directory the G_IO_ERROR_WOULD_MERGE error is returned.

If the source is a directory and the target does not exist, or G_FILE_COPY_OVERWRITE is specified and the target is a file, then the G_IO_ERROR_WOULD_RECURSE error is returned.

If you are interested in copying the GFile object itself (not the on-disk file), see g_file_dup().

Parameters

destination

Type: GFile

Destination GFile.

The data is owned by the caller of the method.

flags

Type: GFileCopyFlags

Set of GFileCopyFlags.

cancellable

Type: GCancellable

Optional GCancellable object, NULL to ignore.

The argument can be NULL.

The data is owned by the caller of the method.

progress_callback

Type: GFileProgressCallback

Function to callback with progress information, or NULL if progress information is not needed.

progress_callback_data

Type: gpointer

User data to pass to progress_callback.

The argument can be NULL.

The data is owned by the caller of the method.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the virtual function if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE on success, FALSE otherwise.
