Returns

0 upon success and -errno upon failure.

Implements XrdOucChkPnt.

int XrdOfsChkPnt::Delete ( )

virtual

Delete a checkpoint.

Returns

0 upon success and -errno upon failure.

Implements XrdOucChkPnt.

int XrdOfsChkPnt::Failed ( const char *  opn, int  rc, bool *  readok  )

private

void XrdOfsChkPnt::Finished ( )

inlinevirtual

Indicate that the checkpointing is finished. Any outstanding checkpoint should be delete and the object should delete itself if necessary.

Implements XrdOucChkPnt.

int XrdOfsChkPnt::Query ( struct iov &  range )

virtual

Query checkpoint limits.

Parameters

range

- reference to where limits are placed. range.length - holds maximum checkpoint length allowed.

Returns

0 upon success and -errno upon failure.

Implements XrdOucChkPnt.

int XrdOfsChkPnt::Restore ( bool *  readok = 0 )

virtual

Restore a checkpoint.

Parameters

readok

- When not nil and an error occurs readok is set true if read access is still allowed; otherwise no access should be allowed.

Returns

0 upon success and -errno upon failure.

Implements XrdOucChkPnt.

virtual

Truncate a file to a specific size.

Parameters

range

- reference to the file truncate size in offset.

Returns

0 upon success and -errno upon failure.

Implements XrdOucChkPnt.

int XrdOfsChkPnt::Write ( struct iov *&  range, int  rnum  )

virtual
