FSize()

long long XrdPosixFile::FSize ( )

inlinevirtual

Implements XrdOucCacheIO.

References AtomicBeg, AtomicEnd, AtomicGet, mySize, and XrdPosixObject::updMutex.

Referenced by XrdPosixPrepIO::FSize().

Fstat()

int XrdPosixFile::Fstat ( struct stat &  sbuff )

virtual

Perform an fstat() operation (defaults to passthrough).

Parameters

sbuff

reference to the stat buffer to be filled in. Only fields st_size, st_blocks, st_mtime (st_atime and st_ctime may be set to st_mtime), st_ino, and st_mode need to be set. All other fields are preset and should not be changed.

Returns

<0 - fstat failed, value is -errno. =0 - fstat succeeded, sbuff holds stat information. >0 - fstat could not be done, forward operation to next level.

Reimplemented from XrdOucCacheIO2.

Referenced by XrdPosixPrepIO::Fstat().

HandleResponse()

void XrdPosixFile::HandleResponse ( XrdCl::XRootDStatus *  status, XrdCl::AnyObject *  response  )

virtual

Called when a response to associated request arrives or an error occurs

Parameters

status	status of the request
response	an object associated with the response (request dependent)

Reimplemented from XrdCl::ResponseHandler.

isOpen()

Location()

const char* XrdPosixFile::Location ( )

virtual

Get the file's location (i.e. endpoint hostname and port)

Returns

A pointer to the file's location. It remains valid until the file is closed. A null string means the file is not open or is unknown.
