XrdOucCacheIO* XrdPosixPrepIO::Base

(

)

[inline, virtual]

Reimplemented from XrdOucCacheIO.

XrdOucCacheIO* XrdPosixPrepIO::Detach

(

)

[inline, virtual]

Reimplemented from XrdOucCacheIO.

void XrdPosixPrepIO::Disable

(

)

long long XrdPosixPrepIO::FSize

(

)

[inline, virtual]

Implements XrdOucCacheIO.

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

int XrdPosixPrepIO::Fstat

(

struct stat &

sbuff

)

[inline, 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.
