Base()

XrdOucCacheIO * XrdPosixPrepIO::Base ( )

inlinevirtual

Reimplemented from XrdOucCacheIO.

Detach()

XrdOucCacheIO * XrdPosixPrepIO::Detach ( )

FSize()

long long XrdPosixPrepIO::FSize ( )

inlinevirtual

Implements XrdOucCacheIO.

References fileP, XrdPosixFile::FSize(), Init(), and openRC.

Fstat()

int XrdPosixPrepIO::Fstat ( struct stat &  sbuff )

inlinevirtual

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.
