Member Function Documentation

Close()

int XrdOssDir::Close ( long long *  retsz = 0 )

virtual

Close a directory or file.

Parameters

retsz

If not nil, where the size of the file is to be returned.

Returns

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

Implements XrdOssDF.

Referenced by ~XrdOssDir().

Opendir()

int XrdOssDir::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 XrdOssDF.

Readdir()

int XrdOssDir::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).

Reimplemented from XrdOssDF.

StatRet()

int XrdOssDir::StatRet ( struct stat *  )

virtual

Set the stat() buffer where stat information is to be placed corresponding to the directory entry returned by Readdir().

Parameters

buff	- Pointer to stat structure to be used.

Returns

0 upon success or -ENOTSUP if not supported.

Note

This is a one-time call as stat structure is reused for each Readdir.

Reimplemented from XrdOssDF.
