Enumerator:

J_ESUCCESS	Success.
J_ENOENT	No such file or directory.
J_ENOJOURNAL	No journal associated with the given file.
J_ENOMEM	Not enough free memory.
J_ECLEANUP	Error cleaning the journal directory.

Function Documentation

enum jfsck_return jfsck	(	const char *	name,
		const char *	jdir,
		struct jfsck_result *	res,
		unsigned int	flags
	)

Check and repair the given path.

The file MUST NOT be in use by any other thread or process. This requirement will be lifted in future releases.

Parameters:

	name	path to the file to check
	jdir	journal directory of the given file, use NULL for the default
	res	structure where to store the result
	flags	flags that change the checking behaviour, currently only J_CLEANUP is supported, which removes the journal directory after a successful recovery

See also:

struct jfsck_result

Returns:

0 on success, < 0 on error, with the following possible negative values from enum jfsck_return: J_ENOENT if there was no such file with the given name, J_ENOJOURNAL if there was no journal at the given jdir, J_ENOMEM if memory could not be allocated, J_ECLEANUP if there was an error cleaning the journal, J_EIO if there was an I/O error.
