FILE DAEMON
4 .FLDXT
5 .FLDPG
6 .FLDDA
7 .FLDPS
10 .FLDPR
This code is set as a result of a previous
call to the File Daemon, which occurred
because a job tried to issue a R, RUN, or GET
command or a RUN monitor call and a protection
error resulted. The File Daemon requested
that the monitor call it when the accessing
program terminates execution. The termination
of a program's execution is defined by the
terminal user or by the batch .CTL file,
either of which may type something that
logically supersedes the core image. The
program may also terminate its own execution
by performing a RUN monitor call. Refer to
Table C-4, flag bit 2.
This code is set because a job tried to
execute a protected program by issuing a R,
RUN, or GET command or a RUN monitor call.
This code is set because a directory
protection failure occurred.
This code is set when a PUSH occurs from a
program that has /EXIT specified.
This code is set when a suspended program
(with /EXIT) resumes with a POP.
The File Daemon responds to the monitor by sending the monitor an IPCF
packet. The packet's message is in the following format:
+---------------------------------------------------------+
1 reserved 1 reserved 1 job number 1
1---------------------------------------------------------I
1 flags 1 0 1 create 1 access 1
+---------------------------------------------------------+
Where:
0-----3 4---8 9-------17 18-------27 28----------35
job number is the number of the job attempting to access a file.
flags are bits 0 through 3 which are described in Table C-4.
create is the protection code at which the file will be
if the specified job is creating a file.
created
access is the highest access this job is allowed to this file.
Refer to Table C-3.
The monitor grants or denies the job's access to the file based on the
access value and the type of access specified by the accessing job.
If the access value in the packet from the File Daemon to the monitor
is greater than or equal to the type of access the accessing job
desired, the monitor grants the job access to the file.
