$DELETE_PROXY
Deletes an existing proxy or removes the default user or a local user
from an existing proxy in the proxy database.
Format
SYS$DELETE_PROXY rem_node ,rem_user ,[local_user] ,[flags]
D Prototype
int sys$delete_proxy (void *rem_node, void *rem_user, void *local_user,
unsigned int flags);
Arguments
rem_node
| OpenVMS usage: |
char_string |
| type: |
character-coded text string |
| access: |
read only |
| mechanism: |
by descriptor--fixed-length string descriptor |
Remote node name of the proxy to be deleted from or modified in the
proxy database. The rem_node argument is the address
of a character-string descriptor pointing to the remote node name
string.
A remote node name consists of 1 to 1024 characters. No specific
characters, format, or case are required for a remote node name string.
All node names are converted to their DECnet for OpenVMS full name
unless the PRX$M_BYPASS_EXPAND flag is set with the
flags argument.
Asterisk (*) and percent sign (%) wildcards are allowed for the remote
node specification. If you specify wildcards for the
rem_node argument, the security server searches for an
exact match to the specified remote node first. If it does not find an
exact match, the server performs the requested operations on all of the
matching proxies in the proxy database.
rem_user
| OpenVMS usage: |
char_string |
| type: |
character-coded text string |
| access: |
read only |
| mechanism: |
by descriptor--fixed-length string descriptor |
Remote user name of the proxy to be deleted from or modified in the
proxy database. The rem_user argument is the address
of a character-string descriptor pointing to the user name string.
A remote user name consists of 1 to 32 alphanumeric characters,
including dollar signs ($), underscores (_), and brackets ([ ]). Any
lowercase characters specified are automatically converted to uppercase.
The rem_user argument can be specified in user
identification code (UIC) format ([group, member]).
Brackets are allowed only if the remote user name string specifies a
UIC. Group and member are character-string representations of octal
numbers with no leading zeros.
Asterisk (*) and percent sign (%) wildcards are allowed for the remote
user specification. If you specify wildcards for the
rem_user argument, the server searches for an exact
match to the specified remote user first. If it does not find an exact
match, the server performs the requested operations on all of the
matching proxies in the proxy database.
local_user
| OpenVMS usage: |
char_string |
| type: |
character-coded text string |
| access: |
read only |
| mechanism: |
by descriptor--fixed-length string descriptor |
Local user name to delete from the proxy record specified by the
rem_node and rem_user arguments in
the proxy database. The local_user argument is the
address of a character-string descriptor pointing to the local user
name.
A local user name consists of 0 to 32 alphanumeric characters,
including dollar signs ($) and underscores (_). If the
local_user argument is not specified or has a length
of 0, the server will delete the entire record or records specified by
the rem_node and rem_user arguments
from the proxy database.
If the local_user argument is specified, the server
will delete only the user name specified by the
local_user argument from the record specified by the
rem_node and rem_user arguments. The
local_user argument can specify either the proxy's
default user or a user name in the proxy's local users list.
flags
| OpenVMS usage: |
mask_longword |
| type: |
longword (unsigned) |
| access: |
read only |
| mechanism: |
by value |
Functional specification for the service and type of user the
local_user argument represents. The
flags argument is a longword bit mask wherein each bit
corresponds to an option.
Each flag option has a symbolic name. The $PRXDEF macro defines the
following symbolic names:
| Symbolic Name |
Description |
|
PRX$M_BYPASS_EXPAND
|
The service should not convert the node name specified in the
rem_node argument to its corresponding DECnet full
name. If this flag is set, it is the caller's responsibility to ensure
that the fully expanded node name is passed into the service.
|
|
PRX$M_IGNORE_RETURN
|
The service should not wait for a return status from the security
server. No return status from the server's function will be returned to
the caller.
|
|
PRX$M_EXACT
|
The service should match exactly the remote node and remote user and
ignore wildcards.
|
Description
The Delete Proxy service deletes a proxy from, or modifies an existing
proxy in, the proxy database.
Required Access or Privileges
$DELETE_PROXY requires access to the proxy database. To achieve access,

$DELETE_REGION_64 (Alpha Only)
On Alpha systems, deletes a virtual region within the process's address
space, including all created virtual addresses within the region.
This service accepts 64-bit addresses.
Format
SYS$DELETE_REGION_64 region_id_64 ,acmode ,return_va_64
,return_length_64
C Prototype
nt sys$delete_region_64 (struct _generic_64 *region_id_64, unsigned int
acmode, void *(*(return_va_64)), unsigned __int64 *return_length_64);
Arguments
region_id_64
| OpenVMS usage: |
region identifier |
| type: |
quadword (unsigned) |
| access: |
read only |
| mechanism: |
by 32- or 64-bit reference |
The region ID associated with the region to be deleted. The region ID
specified must be one returned by the $CREATE_REGION_64 service. You
cannot specify VA$C_P0, VA$C_P1, or VA$C_P2.
acmode
| OpenVMS usage: |
access_mode |
| type: |
longword (unsigned) |
| access: |
read only |
| mechanism: |
by value |
Access mode associated with the call to $DELETE_REGION_64. The
acmode argument is a longword containing the access
mode.
The $PSLDEF macro in STARLET.MLB and the file PSLDEF.H in
SYS$STARLET_C.TLB define the following symbols and their values for the
four access modes:
| Value |
Symbolic Name |
Access Mode |
|

The most privileged access mode used is the access mode of the caller.
The caller can delete pages only if those pages are owned by an access
mode equal to or less privileged than the access mode of the caller.
Once all pages are deleted within the region, the region can be deleted
only if the region is owned by an access mode equal to or less
privileged than the access mode of the caller.
return_va_64
| OpenVMS usage: |
address |
| type: |
quadword address |
| access: |
write only |
| mechanism: |
by 32- or 64-bit reference |
The lowest process virtual address of the pages that $DELETE_REGION_64
has successfully deleted. The return_va_64 argument is
the 32- or 64-bit virtual address of a naturally aligned quadword into
which the service returns the virtual address of the first page
deleted. Virtual addresses are deleted from low address to high
address, regardless of the direction in which virtual addresses expand
for that region.
return_length_64
| OpenVMS usage: |
byte count |
| type: |
quadword (unsigned) |
| access: |
write only |
| mechanism: |
by 32- or 64-bit reference |
The length of the virtual address range that $DELETE_REGION_64 has
successfully deleted. The return_length_64 argument is
the 32- or 64-bit virtual address of a naturally aligned quadword into
which the service returns the length of the deleted virtual address
range in bytes.
Description
The Delete a Virtual Region service is a kernel mode service that can
be called from any mode. This service deletes the user-defined region
specified by the region_id_64 argument. You cannot
delete the program (P0), control (P1), or 64-bit program (P2) regions.
The Delete a Virtual Region service also deletes all created virtual
addresses within the specified region before deleting the region itself.
If a page within the region is owned by an access mode more privileged
than the access mode of the caller, the condition value SS$_PAGOWNVIO
is returned. The return_va_64 and
return_length_64 arguments contain the virtual address
range that was actually deleted by $DELETE_REGION_64. In this case, the
region is not deleted because there are still some pages mapped within
the region.
To delete a virtual region, the caller's access mode must be at least
as privileged as the access mode associated with the region. If the
caller is not privileged enough to delete the region, the condition
value SS$_REGOWNVIO is returned only if all pages were successfully
deleted from within the region.
If the condition value SS$_ACCVIO is returned by this service, a value
cannot be returned in the memory locations pointed to by the
return_va_64 and return_length_64
arguments. If the condition value SS$_ACCVIO is returned, no pages have
been deleted, and the region has not been deleted.
If an error other than SS$_ACCVIO occurs, the returned address and
returned length indicate the pages that were successfully deleted
before the error occurred. If no pages were deleted, the
return_va_64 argument contains the value --1 and a
value cannot be returned in the memory location pointed to by
the return_length_64 argument.

$DELLNM
Deletes all logical names with the specified name at the specified
access mode or outer access mode, or it deletes all the logical names
with the specified access mode or outer access mode in a specified
table.
On Alpha systems, this service accepts 64-bit addresses.
Format
SYS$DELLNM tabnam ,[lognam] ,[acmode]
C Prototype
int sys$dellnm (void *tabnam, void *lognam, unsigned char *acmode);
Arguments
tabnam
| OpenVMS usage: |
logical_name |
| type: |
character-coded text string |
| access: |
read only |
| mechanism: |
by 32- or 64-bit descriptor--fixed-length string descriptor
(Alpha) |
| mechanism: |
by 32-bit descriptor--fixed-length string descriptor
(VAX) |
Name of a logical name table or a list of tables to be searched for the
logical name to be deleted. The tabnam argument is the
32-bit address (on VAX systems) or the 32- or 64-bit address (on Alpha
systems) of a descriptor that points to the table name. This argument
is required.
If tabnam is not the name of a logical name table, it
is assumed to be a logical name and is translated iteratively until
either the name of a logical name table is found or the number of
translations allowed by the system has been performed.
If tabnam translates to the name of a list of tables,
$DELLNM does the following:
- If you specify the lognam argument, $DELLNM
searches (in order) each table in the list until it finds the first
table that contains the specified logical name. If the logical name is
at the specified access mode, $DELLNM then deletes occurrences of the
logical name at the specified access mode and at outer access modes
within the table.
- If you do not specify the lognam argument, $DELLNM
deletes all of the logical names at the specified access mode or at
outer access modes from the first table in the list whose access mode
is equal to or less privileged than the caller's access mode.
lognam
| OpenVMS usage: |
logical_name |
| type: |
character-coded text string |
| access: |
read only |
| mechanism: |
by 32- or 64-bit descriptor--fixed-length string descriptor
(Alpha) |
| mechanism: |
by 32-bit descriptor--fixed-length string descriptor
(VAX) |
Logical name to be deleted. The lognam argument is the
32-bit address (on VAX systems) or the 32- or 64-bit address (on Alpha
systems) of a descriptor that points to the logical name string.
acmode
| OpenVMS usage: |
access_mode |
| type: |
byte (unsigned) |
| access: |
read only |
| mechanism: |
by 32- or 64-bit reference (Alpha) |
| mechanism: |
by 32-bit reference (VAX) |
Access mode to be used in the delete operation. The
acmode argument is the 32-bit address (on VAX systems)
or the 32- or 64-bit address (on Alpha systems) of a byte containing
this access mode. The $PSLDEF macro defines symbolic names for the four
access modes.
You determine the access mode actually used in the delete operation by
maximizing the access mode of the caller with the access mode
specified by the acmode argument; that is, the less
privileged of the two is used.
However, if you have SYSNAM privilege, the delete operation is executed
at the specified access mode regardless of the caller's access mode.
If you omit this argument or specify it as 0, the access mode of the
caller is used in the delete operation. The access mode used in the
delete operation determines which tables are used and which names are
deleted.
Description
The Delete Logical Name service deletes all logical names with the
specified name at the specified access mode or outer access mode, or it
deletes all the logical names with the specified access mode or outer
access mode in a specified table. If any logical names being deleted
are also the names of logical name tables, then all of the logical
names contained within those tables and all of their subtables are also
deleted.
Required Access or Privileges
Depending on the operation, the calling process might need one of the
following access or rights privileges to use $DELLNM:
- Write and delete access to the logical name table to delete a
logical name
- Write access to the directory table that contains the table name,
or SYSPRV privilege, to delete a shareable logical name table
- SYSNAM privilege to delete a logical name or table at an inner
access mode
- GRPNAM or SYSPRV privilege to delete a logical name from a group
table
- SYSNAM or SYSPRV privilege to delete a logical name from a system
table
