SBK$L_STLBN | | Contains the starting LBN of the file
if the file is contiguous. If the file is not contiguous, this field
contains a value of 0. The LBN appears as an inverted longword (the
high- and low-order 16 bits are transposed for PDP-11 compatibility).
The following subfields are defined: |
| | SBK$W_STLBNH | Starting LBN (high-order 16 bits) |
| | SBK$W_STLBNL | Starting LBN (low-order 16 bits) |
SBK$L_FILESIZE | | Contains the size of the file in blocks.
The file size appears as an inverted longword (the high- and low-order
16 bits are transposed for PDP-11 compatibility). The following subfields
are defined: |
| | SBK$W_FILESIZH | File size (high-order 16 bits) |
| | SBK$W_FILESIZL | File size (low-order 16 bits) |
SBK$B_ACNT[1] | | Access count (low byte).
Field is for PDP-11 compatibility. |
SBK$B_LCNT[1] | | Lock count
(low byte). Field is for PDP-11 compatibility. |
SBK$L_FCB | | System pool address of the file's
file control block. |
SBK$W_ACNT[1] | | Access count
(number of channels with file open currently). |
SBK$W_LCNT[1] | | Lock count
(the number of access operations that have locked the file against
writers). |
SBK$W_WCN[1] | | Writer count
(the number of channels that currently have the file open for write). |
SBK$W_TCNT[1] | | Truncate lock
count (the number of access operations that have locked the file against
truncation). |
SBK$L_READS | | Number of read operations executed for
the file on this channel. |
SBK$L_WRITES | | Number of write operations executed for the file on this channel. |
