F$GETQUI() is a lexical function that returns information about queues, including batch and print jobs currently in the queues, form definitions, characteristic definitions kept in the queue database, and queue managers. For most operations, read access is required.
Brackets () denote an optional argument. Some function arguments cannot be specified with the item-code, the object-id, or the flags argument; visit the function section below for more information.
Specifies the action that the F$GETQUI lexical function is to perform. F$GETQUI supports all functions that can be specified with the $GETQUI system service. The following table lists these functions:
|CANCEL_OPERATION||Terminates any wildcard operation that may have been initiated by a previous call to F$GETQUI.|
|DISPLAY_CHARACTERISTIC||Returns information about a specific characteristic definition or the next characteristic definition in a wildcard operation.|
|DISPLAY_ENTRY||Returns information about a specific job entry or the next job entry that matches the selection criteria in a wildcard operation. The DISPLAY_ENTRY function code is similar to the DISPLAY_JOB function code in that both return job information. DISPLAY_JOB, however, requires that a call be made to establish queue context; DISPLAY_ENTRY does not require that queue context be established. Only those entries that match the user-name of the current process will be processed.|
|DISPLAY_FILE||Returns information about the next file defined for the current job context. Before you make a call to F$GETQUI to request file information, you must make a call to display queue and job information (with the DISPLAY_QUEUE and DISPLAY_JOB function codes) or to display entry information (with the DISPLAY_ENTRY function code).|
|DISPLAY_FORM||Returns information about a specific form definition or the next form definition in a wildcard operation.|
|DISPLAY_JOB||Returns information about the next job defined for the current queue context. Before you make a call to F$GETQUI to request job information, you must make a call to display queue information (with the DISPLAY_QUEUE function code). The DISPLAY_JOB function code is similar to the DISPLAY_ENTRY function code in that both return job information. DISPLAY_JOB, however, requires that a call be made to establish queue context; DISPLAY_ENTRY does not require that queue context be established.|
|DISPLAY_MANAGER||Returns information about a specific queue manager or the next queue manager in a wildcard operation.|
|DISPLAY_QUEUE||Returns information about a specific queue definition or the next queue definition in a wildcard operation.|
|TRANSLATE_QUEUE||Translates a logical name for a queue to the equivalence name for the queue.|
Some function arguments cannot be specified with the item-code, the object-id, or the flags argument. The following table lists each function argument and corresponding format line to show whether the item-code, object-id, and flags arguments are required, optional, or not applicable for that specific function. In the following format lines, brackets ([ ]) denote an optional argument. An omitted argument means the argument is not applicable for that function. Note that two commas (,,) must be used as placeholders to denote an omitted (whether optional or not applicable) argument.
|CANCEL_OPERATION||F$GETQUI("CANCEL_OPERATION") or F$GETQUI(" ")|
Corresponds to a $GETQUI system service output item code. The item argument specifies the kind of information you want returned about a particular queue, job, file, form, or characteristic.
Corresponds to the $GETQUI system service QUI$SEARCH_NAME, QUI$_SEARCH_NUMBER, and QUI$_SEARCH_JOB_NAME input item codes. The object-id argument specifies either the name or the number of an object (for example, a specific queue name, job name, or form number) about which F$GETQUI is to return information. The asterisk (*) and the percent sign (%) wildcard characters are allowed for the following functions:
DISPLAY_CHARACTERISTIC DISPLAY_ENTRY DISPLAY_FORM DISPLAY_MANAGER DISPLAY_QUEUE
By specifying an asterisk (*) or percent sign (%) wildcard character as the object-id argument on successive calls, you can get status information about one or more jobs in a specific queue or about files within jobs in a specific queue. When a name is used with wildcard characters, each call returns information for the next object (queue, form, and so on) in the list. A null string ("") is returned when the end of the list is reached. A wildcard can represent only object names, not object numbers.
Specifies a list of keywords, separated by commas, that corresponds to the flags defined for the $GETQUI system service QUI$_SEARCH_FLAGS input item code. (These flags are used to define the scope of the object search specified in the call to the $GETQUI system service.) Note that the keywords can be used only with certain function codes.
