Detailed Description

Directory class for Fat32Fs

Constructor & Destructor Documentation

miosix::Fat32Directory::Fat32Directory	(	intrusive_ref_ptr< FilesystemBase >	parent,
		FastMutex &	mutex,
		int	currentInode,
		int	parentInode
	)

inline

Parameters

parent	parent filesystem
mutex	mutex to lock when accessing the fiesystem
currentInode	inode value for '.' entry
parentInode	inode value for '..' entry

miosix::Fat32Directory::~Fat32Directory ( )

virtual

Destructor

DIR_* miosix::Fat32Directory::directory ( )

inline

int miosix::Fat32Directory::getdents	(	void *	dp,
		int	len
	)

virtual

Also directories can be opened as files. In this case, this system call allows to retrieve directory entries.

Parameters

dp	pointer to a memory buffer where one or more struct dirent will be placed. dp must be four words aligned.
len	memory buffer size.

Returns: the number of bytes read on success, or a negative number on failure.
