Opendir()

int XrdOssCsiDir::Opendir ( const char * path, XrdOucEnv & env )

virtual

Open a directory.

Parameters

path	- Pointer to the path of the directory to be opened.
env	- Reference to environmental information.

Returns

0 upon success or -errno or -osserr (see XrdOssError.hh).

Reimplemented from XrdOssDFHandler.

Readdir()

int XrdOssCsiDir::Readdir ( char * buff, int blen )

virtual

Get the next directory entry.

Parameters

buff	- Pointer to buffer where a null terminated string of the entry name is to be returned. If no more entries exist, a null string is returned.
blen	- Length of the buffer.

Returns

0 upon success or -errno or -osserr (see XrdOssError.hh).
