Function Documentation

◆ eio_file_chmod()

EIO_API Eio_File * eio_file_chmod	(	const char *	path,
		mode_t	mode,
		Eio_Done_Cb	done_cb,
		Eio_Error_Cb	error_cb,
		const void *	data
	)

Change rights of a path.

Parameters

path	The directory path to change access rights.
mode	The permission to set, follow (mode & ~umask & 0777).
done_cb	Callback called when the operation is completed.
error_cb	Callback called from if something goes wrong.
data	Unmodified user data passed to callbacks.

Returns: A reference to the I/O operation.

Set a new permission of a path changing it to the mode passed as argument. It's equivalent to the chmod command.

◆ eio_file_chown()

EIO_API Eio_File * eio_file_chown	(	const char *	path,
		const char *	user,
		const char *	group,
		Eio_Done_Cb	done_cb,
		Eio_Error_Cb	error_cb,
		const void *	data
	)

Change owner of a path.

Parameters

path	The directory path to change owner.
user	The new user to set (can be NULL).
group	The new group to set (can be NULL).
done_cb	Callback called when the operation is completed.
error_cb	Callback called from if something goes wrong.
data	Unmodified user data passed to callbacks

Returns: A reference to the I/O operation.

This function will change the owner of a path, setting it to the user and group passed as argument. It's equivalent to the chown shell command.

Note: Some platforms (including Windows) do not support chown(). In that case, this function returns NULL.

◆ eio_file_unlink()

EIO_API Eio_File * eio_file_unlink	(	const char *	path,
		Eio_Done_Cb	done_cb,
		Eio_Error_Cb	error_cb,
		const void *	data
	)

Unlink a file/directory.

Parameters

path	The path to unlink.
done_cb	Callback called when the operation is completed.
error_cb	Callback called from if something goes wrong.
data	Unmodified user data passed to callbacks.

Returns: A reference to the I/O operation.

This function will erase a file.

◆ eio_file_mkdir()

EIO_API Eio_File * eio_file_mkdir	(	const char *	path,
		mode_t	mode,
		Eio_Done_Cb	done_cb,
		Eio_Error_Cb	error_cb,
		const void *	data
	)

Create a new directory.

Parameters

path	The directory path to create.
mode	The permission to set, follow (mode & ~umask & 0777).
done_cb	Callback called when the operation is completed.
error_cb	Callback called from if something goes wrong.
data	Unmodified user data passed to callbacks

Returns: A reference to the I/O operation.

Creates a new directory using the mode provided.

◆ eio_file_move()

EIO_API Eio_File * eio_file_move	(	const char *	source,
		const char *	dest,
		Eio_Progress_Cb	progress_cb,
		Eio_Done_Cb	done_cb,
		Eio_Error_Cb	error_cb,
		const void *	data
	)

Move a file asynchronously.

Parameters

source	Should be the name of the file to move the data from.
dest	Should be the name of the file to move the data to.
progress_cb	Callback called to know the progress of the move.
done_cb	Callback called when the move is done.
error_cb	Callback called when something goes wrong.
data	Unmodified user data passed to callbacks

Returns: A reference to the I/O operation.; an Eio_File pointer, handler to the move operation, can be used to cancel the operation

This function will copy a file from source to dest. It will try to use splice if possible, if not it will fallback to mmap/write. It will try to preserve access rights, but not user/group identification.

◆ eio_file_copy()

EIO_API Eio_File * eio_file_copy	(	const char *	source,
		const char *	dest,
		Eio_Progress_Cb	progress_cb,
		Eio_Done_Cb	done_cb,
		Eio_Error_Cb	error_cb,
		const void *	data
	)

Copy a file asynchronously.

Parameters

source	Should be the name of the file to copy the data from.
dest	Should be the name of the file to copy the data to.
progress_cb	Callback called to know the progress of the copy.
done_cb	Callback called when the copy is done.
error_cb	Callback called when something goes wrong.
data	Unmodified user data passed to callbacks

Returns: an Eio_File pointer, handler to the copy operation, can be used to cancel the operation

This function will copy a file from source to dest. It will try to use splice if possible, if not it will fallback to mmap/write. It will try to preserve access rights, but not user/group identification.

◆ eio_dir_move()

EIO_API Eio_File * eio_dir_move	(	const char *	source,
		const char *	dest,
		Eio_Filter_Direct_Cb	filter_cb,
		Eio_Progress_Cb	progress_cb,
		Eio_Done_Cb	done_cb,
		Eio_Error_Cb	error_cb,
		const void *	data
	)

Move a directory and its content asynchronously.

Parameters

source	Should be the name of the directory to copy the data from.
dest	Should be the name of the directory to copy the data to.
filter_cb	Possible to deny the move of some files/directories.
progress_cb	Callback called to know the progress of the copy.
done_cb	Callback called when the copy is done.
error_cb	Callback called when something goes wrong.
data	Unmodified user data passed to callbacks

Returns: A reference to the I/O operation.; an Eio_File pointer, handler to the move operation, can be used to cancel the operation

This function will move a directory and all its content from source to dest. It will try first to rename the directory, if not it will try to use splice if possible, if not it will fallback to mmap/write. It will try to preserve access rights, but not user/group identity. Every file will be passed to the filter_cb, so it's your job to decide if you want to pass the file to the main_cb or not. Return EINA_TRUE to pass it to the main_cb or EINA_FALSE to ignore it.

Note: if a rename occurs, the filter callback will not be called.

◆ eio_dir_copy()

EIO_API Eio_File * eio_dir_copy	(	const char *	source,
		const char *	dest,
		Eio_Filter_Direct_Cb	filter_cb,

		Eio_Error_Cb	error_cb,
		const void *	data
	)

Copy a directory and its content asynchronously.

Parameters

source	Should be the name of the directory to copy the data from.
dest	Should be the name of the directory to copy the data to.
filter_cb	Possible to deny the move of some files/directories.
progress_cb	Callback called to know the progress of the copy.
done_cb	Callback called when the copy is done.
error_cb	Callback called when something goes wrong.
data	Unmodified user data passed to callbacks

Returns: A reference to the I/O operation.; an Eio_File pointer, handler to the copy operation, can be used to cancel the operation

This function will copy a directory and all its content from source to dest. It will try to use splice if possible, if not it will fallback to mmap/write. It will try to preserve access rights, but not user/group identity. Every file will be passed to the filter_cb, so it's your job to decide if you want to pass the file to the main_cb or not. Return EINA_TRUE to pass it to the main_cb or EINA_FALSE to ignore it.

◆ eio_dir_unlink()

EIO_API Eio_File * eio_dir_unlink	(	const char *	path,
		Eio_Filter_Direct_Cb	filter_cb,
		Eio_Progress_Cb	progress_cb,
		Eio_Done_Cb	done_cb,
		Eio_Error_Cb	error_cb,
		const void *	data
	)

Remove a directory and its content asynchronously.
