Member Function Documentation

Close()

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

overridevirtual

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.

Definition at line 18 of file XrdOssMirageDir.cc.

{
    return -ENOTSUP;
}

Opendir()

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

overridevirtual

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.

Definition at line 3 of file XrdOssMirageDir.cc.

{
    return -ENOTSUP;
}

Readdir()

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

overridevirtual

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.

Definition at line 8 of file XrdOssMirageDir.cc.

{
    return -ENOTSUP;
}

StatRet()

int XrdOssMirageDir::StatRet ( struct stat * buff )

overridevirtual

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.

When StatRet() is in effect, directory entries that have been deleted from the target directory are quietly skipped.

Reimplemented from XrdOssDF.

Definition at line 13 of file XrdOssMirageDir.cc.

{
    return -ENOTSUP;
}
