ignore_overwrite_restrictions_for_next_write()

void libdar::filesystem_restore::ignore_overwrite_restrictions_for_next_write ( )

inline

ask for no warning or user interaction for the next write operation

Note

this is used when a file has been saved several times due to its changes at the time of the backup and is restored in sequential read. Restoring each failed backup would lead to ask each time the actions to take about overwriting... anoying for the user

Definition at line 123 of file filesystem_restore.hpp.

write()

void libdar::filesystem_restore::write	(	const cat_entree *	x,
		action_done_for_data &	data_restored,
		bool &	ea_restored,
		bool &	data_created,
		bool &	hard_link,
		bool &	fsa_restored
	)

restore a libdar object to a filesystem entry both data and EA

Parameters

[in]	x	is the libdar object to restore
[out]	data_restored	true if data has been restored (inode or hard link created), false if either there is no data to restore or if this action is forbidden by the overwriting policy
[out]	ea_restored	true if EA has been restored, false if either no EA to restore or if forbidden by overwriting policy
[out]	data_created	true if data has been restored leading to file creation, false in any other case
[out]	hard_link	true when data_restored is true and only a hard link to an already existing inode has been created
[out]	fsa_restored	true if FSA has been restored, false if either no FSA to restore or if forbidden by overwriting policy

Note

any failure to restore data or EA that is not due to its absence in "x" nor to an interdiction from the overwriting policy is signaled through an exception.
