Deletes a persona created using the $PERSONA_CREATE, the $PERSONA_CLONE, or the $PERSONA_RESERVE service.
SYS$PERSONA_DELETE persona
int sys$persona_delete (unsigned int *persona);
persona
OpenVMS usage: persona type: longword (unsigned) access: read only mechanism: by reference
Address of a longword in which the persona identification handle is expected.
The PERSONA_DELETE service frees the resources used by the persona. No changes to the caller's process are made as a result of calling $PERSONA_DELETE.The persona argument is validated against the caller's mode, so an invalid argument can cause an access violation to be signaled.

SS$_NORMAL The service completed successfully. SS$_ACCVIO Access violation. SS$_PERSONADELPEND Persona is in use; delete pending on release. SS$_NODELPERMANENT Permanent personae cannot be deleted.
On Alpha and I64 systems, deletes an extension attached to a persona.
SYS$PERSONA_DELETE_EXTENSION persona ,extensionID
int sys$persona_delete_extension (unsigned int *persona, unsigned int *extensionID);
persona
OpenVMS usage: persona type: longword (unsigned) access: read only mechanism: by reference
Address of a longword containing the persona identification for which $PERSONA_DELETE_EXTENSION calls the registered Extension Delete function.extensionID
OpenVMS usage: extension_ID type: longword (unsigned) access: read only mechanism: by reference
Address of a longword containing the extension identification (EID) for which the registered DELETE routine is called in order to delete a persona extension block from the specified persona.
This service deletes an extension data structure by calling the registered Extension Delete routine for the specified extension.When a return fails, the persona extension is not deleted.
The VMS extension associated with each persona cannot be deleted. An attempt to delete that extension returns SS$_UNSUPPORTED.
This service requires that the caller have the IMPERSONATE privilege enabled or be in exec or kernel mode.

On Alpha and I64 systems, translates a text name of an extension (for example, VMS or NT) into an extension identification (EID) that can be used in other persona-related system services.
SYS$PERSONA_EXTENSION_LOOKUP extensionName ,extensionID
int sys$persona_extension_lookup (void *extensionName, unsigned int *extensionID);
extensionName
OpenVMS usage: extension_name type: character-coded text string access: read only mechanism: by descriptor--fixed-length descriptor
Address of a character string descriptor pointing to the name of the extension being looked up.extensionID
OpenVMS usage: extension_ID type: longword (unsigned) access: write only mechanism: by reference
Address of a longword into which the value of the extension identification (EID) returned by the service is written.
This service translates a text name of an extension into an extension identification (EID) that can be used in other persona-related system services.There are currently two extension names: VMS and NT.

On Alpha and I64 systems, enables the caller to find the personae within a process that have certain attributes or settings.
SYS$PERSONA_FIND persona ,itmlst ,contxt
int sys$persona_find (unsigned int *persona, void *itmlst, unsigned int *contxt);
persona
OpenVMS usage: persona type: longword (unsigned) access: write only mechanism: by reference
Address of a longword into which the persona identification that matches all of the items present in the item list is written.itmlst
OpenVMS usage: item_list_3 type: longword (unsigned) access: read only mechanism: by reference
Attributes specifying which information about the persona is to be compared. The itmlst argument is the address of a list of item descriptors, each describing an item of information or an item list processing directive. The list of item descriptors is terminated by a longword value of 0.The following diagram shows the format of a single item descriptor:
The following table lists the item descriptor fields and their definitions:
| Field | Description |
|---|---|
| Buffer length | A word containing a user-supplied integer specifying the length (in bytes) of the buffer in which $PERSONA_FIND is to locate the information. The length of the buffer depends on the item code specified in the item code field of the item descriptor. If the value of buffer length is too small, $PERSONA_FIND fails the comparison. |
| Item code | A word containing a user-supplied symbolic code specifying the item of information $PERSONA_FIND is to test, or specifying a directive for processing subsequent items. The $ISSDEF macro defines these codes. Each item code is described in the Description section. |
| Buffer address | A longword containing the user-supplied address of the buffer in which $PERSONA_FIND locates the information used for the comparison. |
| Return length address | An unused longword containing the user-supplied address of a word into which the system service writes the length in bytes of the information it returned. This longword is unused for PERSONA_FIND. |
| OpenVMS usage: | context |
| type: | longword (unsigned) |
| access: | modify |
| mechanism: | by reference |
This service enables the caller to find the personae within a process that have certain attributes or settings.A persona identification is returned only if all the items specified in the item list match those in the persona and its extensions.
The item list cannot be changed between context-saved calls. Results are unpredictable if the item list is changed between calls.
Repeated calls to $PERSONA_FIND return subsequent matching personae. When the service returns SS$_NOMOREPROC, there are no more personae to examine.
OpenVMS Persona Item Codes
The following table contains the item codes specific to the OpenVMS persona extension data:
Item Code Use+ Size (bytes) Description ISS$_USERNAME Q,M,F 32 OpenVMS user name as text string ISS$_ACCOUNT Q,M,F 32 OpenVMS account name as text string ISS$_DOMAIN Q,F 32 OpenVMS SCSNODE as text string as obtained from $GETJPI's nodename ISS$_PRINCIPAL Q,F 64 OpenVMS user name as text string ISS$_EXTENSION Q,F 32 The text string VMS ISS$_WORKPRIV Q,M 8 Working privilege mask ISS$_WORKCLASS Q,M Varying Working classification ISS$_RIGHTS Q Varying Enabled list of rights identifiers ISS$_NOAUDIT Q,M 4 No audit counter---0 means audits disabled ISS$_UIC Q,M,F 4 Current UIC ISS$_AUTHPRIV Q,M 8 Authorized privilege mask ISS$_PERMPRIV Q,M 8 Permanent privilege mask ISS$_IMAGE_WORKPRIV Q,M 8 Image working privilege mask ISS$_ENABLED Q 4 Mask of enabled rights chains ISS$_AUTHRIGHTS Q Varying Authorized list of rights identifiers ISS$_MINCLASS Q Varying Minimum classification ISS$_MAXCLASS Q Varying Maximum classification
