Function Documentation

void cache_purge	(	cache_object_t **	root,
		const char *	path
	)

Purge all cache object at/below a given path.

Methods that need to invalidate cache lines:

• setpath (when create is on)
• put
• put_file
• del
• rename

int get_cache_object	(	const obexftp_client_t *	cli,
		const char *	name,
		char **	object,
		int *	size
	)

Retrieve an object from the cache.

int obexftp_closedir

(

void *

dir

)

Close a directory after reading.

The stat entry is a cache object so we do nothing.

void* obexftp_opendir	(	obexftp_client_t *	cli,
		const char *	name
	)

Prepare a directory for reading.

stat_entry_t* obexftp_readdir

(

void *

dir

)

Read the next entry from an open directory.

stat_entry_t* obexftp_stat	(	obexftp_client_t *	cli,
		const char *	name
	)

Stat a directory entry.

int put_cache_object	(	obexftp_client_t *	cli,
		char *	name,
		char *	object,
		int	size
	)

Store an object in the cache.
