Eio_Filter_Direct_Cb  filter_cb,
Eio_Progress_Cb  progress_cb,
Eio_Done_Cb  done_cb,
Eio_Error_Cb  error_cb,

)

Copy a directory and its content asynchronously.

Parameters:
sourceShould be the name of the directory to copy the data from.
destShould be the name of the directory to copy the data to.
filter_cbPossible to deny the move of some files/directories.
progress_cbCallback called to know the progress of the copy.
done_cbCallback called when the copy is done.
error_cbCallback called when something goes wrong.
dataUnmodified 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_Progress_Cb  progress_cb,
Eio_Done_Cb  done_cb,
Eio_Error_Cb  error_cb,

)

Move a directory and its content asynchronously.

Parameters:
sourceShould be the name of the directory to copy the data from.
destShould be the name of the directory to copy the data to.
filter_cbPossible to deny the move of some files/directories.
progress_cbCallback called to know the progress of the copy.
done_cbCallback called when the copy is done.
error_cbCallback called when something goes wrong.
dataUnmodified 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.

Remove a directory and its content asynchronously.

Parameters:
pathShould be the name of the directory to destroy.
filter_cbPossible to deny the move of some files/directories.
progress_cbCallback called to know the progress of the copy.
done_cbCallback called when the copy is done.
error_cbCallback called when something goes wrong.
dataUnmodified user data passed to callbacks
Returns:
A reference to the I/O operation.

This function will remove a directory and all its content. 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.

)

Change rights of a path.

Parameters:
pathThe directory path to change access rights.
modeThe permission to set, follow (mode & ~umask & 0777).
done_cbCallback called when the operation is completed.
error_cbCallback called from if something goes wrong.
dataUnmodified 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.

Change owner of a path.

Parameters:
pathThe directory path to change owner.
userThe new user to set (can be NULL).
groupThe new group to set (can be NULL).
done_cbCallback called when the operation is completed.
error_cbCallback called from if something goes wrong.
dataUnmodified 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.
