HP OpenVMS System Services Reference Manual

$GETTIM_PREC

Returns the current high precision system time in a 64-bit format.
On Alpha and Integrity server systems, this service accepts 64-bit addresses.

Format

SYS$GETTIM_PREC timadr

C Prototype

int sys$gettim_prec (struct _generic_64 *timadr);

Argument

timadr

OpenVMS usage: date_time

type: quadword (unsigned)

access: write only

mechanism: by 64-bit reference

The 64-bit address of a quadword to receive the current time in 64-bit format.

Description

The Get Time Precision service returns the current system time in 64-bit format. The quadword is the number of 100 nanoseconds since November 17, 1858.
On Alpha and Integrity server systems, the frequency at which system time is updated varies, depending on the clock frequency of the Alpha or Integrity server processor, or approximately 1 millisecond.
On Integrity servers, $GETTIM_PREC returns the system time after accounting for the time elapsed since the last one millisecond update of the system time.
On Alpha, this service is equivalent to $GETTIM service and just returns the last updated system time. The successful completion status of the service on ALPHA is SS$_LOWPREC.

For additional information about the system time, see the HP OpenVMS System Manager's Manual.

Condition Values Returned

SS$_NORMAL The service completed successfully.

SS$_LOWPREC The platform does not support high precision time or it is not possible to return high precision time at this point. The time returned is just the low precision time after successful completion of the service.

SS$_ACCVIO The quadword to receive the time cannot be written by the caller.

$GETUAI

Returns authorization information about a specified user.

Format

SYS$GETUAI [nullarg] ,[contxt] ,usrnam ,itmlst ,[nullarg] ,[nullarg] ,[nullarg]

C Prototype

int sys$getuai (unsigned int efn, unsigned int *contxt, void *usrnam, void *itmlst, struct _iosb *iosb, void (*astadr)(__unknown_params), int astprm);

Arguments

nullarg

OpenVMS usage: null_arg

type: longword (unsigned)

access: read only

mechanism: by value

Placeholding argument reserved to HP.
contxt

OpenVMS usage: longword

type: longword (unsigned)

access: modify

mechanism: by reference

An optional longword used to maintain an open channel to the authorization file. The contxt argument is the address of a longword to receive a $GETUAI context value. If the contxt argument is specified on the initial call, this longword should contain the value --1, and on subsequent calls, the value of the contxt argument from the previous call should be passed back in.
usrnam

OpenVMS usage: char_string

type: character-coded text string

access: read only

mechanism: by descriptor--fixed-length string descriptor

Name of the user about whom $GETUAI returns authorization information. The usrnam argument is the address of a descriptor pointing to a character text string containing the user name. The user name string can contain a maximum of 12 alphanumeric characters.
itmlst

OpenVMS usage: item_list_3

type: longword (unsigned)

access: read only

mechanism: by reference

Item list specifying which information from the specified user's user authorization file (UAF) record is to be returned. The itmlst argument is the address of a list of one or more item descriptors, each of which specifies an item code. The item list is terminated by an item code value of 0 or by a longword value of 0.
The following diagram depicts the structure of a single item descriptor:

The following table defines the item descriptor fields:

Descriptor Field Definition

Buffer length A word specifying the length (in bytes) of the buffer in which $GETUAI is to write the information. The length of the buffer varies, depending on the item code specified in the item code field of the item descriptor, and is given in the description of each item code. If the value of the buffer length field is too small, $GETUAI truncates the data.

Item code A word containing a user-supplied symbolic code specifying the item of information that $GETUAI is to return. The $UAIDEF macro defines these codes.

Buffer address A longword containing the user-supplied address of the buffer in which $GETUAI is to write the information.

Return length address A longword containing the user-supplied address of a word in which $GETUAI writes the length in bytes of the information it actually returned.
