The Get User Authorization Information service returns authorization information about a specified user.Required Access or Privileges
Use the following list to determine the privileges required to use the $GETUAI service:
- BYPASS or SYSPRV---Allows access to any record in the user authorization file (UAF).
- GRPPRV---Allows access to any record in the UAF whose UIC group matches that of the requester.
- No privilege---Allows access to any UAF record whose UIC matches that of the requester.
You need read access to the UAF to look up any information other than your own.Required Quota

SS$_NORMAL The service completed successfully. SS$_ACCVIO The item list or input buffer cannot be read by the caller; or the return length buffer, output buffer, or status block cannot be written by the caller. SS$_BADPARAM The function code is invalid; the item list contains an invalid item code; a buffer descriptor has an invalid length; or the reserved parameter has a nonzero value. SS$_NOGRPPRV The user does not have the privileges required to examine the authorization information for other members of the UIC group. SS$_NOSYSPRV The user does not have the privileges required to examine the authorization information associated with the user or for users outside of the user's UIC group. RMS$_RSZ The UAF record is smaller than required; the caller's SYSUAF is probably corrupt.
This service can also return OpenVMS RMS status codes associated with operations on indexed files. For example, an inquiry about a nonexistent account returns RMS$_RNF, record not found status. For a description of RMS status codes that are returned by this service, refer to the OpenVMS Record Management Services Reference Manual.

buffer
OpenVMS usage: address type: longword (unsigned) access: read/write mechanism: by 32- or 64-bit reference

OpenVMS usage: longword_signed type: longword (signed) access: write mechanism: by 32- or 64-bit reference
The amount of data, in bytes, stored in the buffer. The return_size argument is the 32- or 64-bit address of a naturally aligned longword into which the service returns the size of the buffer. The return_size is set to 0 if there is no data in the buffer.
The Get Alignment Fault Data service obtains data from the user image alignment fault buffer if buffered user alignment fault data reporting has been enabled.When buffered user alignment fault data reporting is enabled, the operating system writes each alignment fault into a user-defined buffer. The user must poll this buffer periodically to read the data.
The user must call the $START_ALIGN_FAULT_REPORT service to enable buffered user alignment fault data reporting.
For more information about buffered user alignment fault data reporting, see the $START_ALIGN_FAULT_REPORT system service.
