$FiStatL
Retrieve set of files' statistics into list
Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $FiStatL function.
This function allows retrieval of statistics for a set of files into a $list.
The $FiStatL function accepts three arguments and returns a numeric error code.
The first argument is the identifier of the $list that is to receive the results. The current contents of the $list are deleted and replaced with the requested statistics. The format of each $list item is:
| Byte 1-10 | Blank padded file name |
|---|---|
| Byte 11-12 | Binary file number |
| Byte 13- | Returned statistics |
The second argument is a string of blank-delimited words indicating the statistics to be returned. The length of each returned statistic is always a multiple of 4 bytes. This facilitates the use of $StatLD $StatLD with the returned $list. For more information on available statistics, see the SirMon User's Guide.
The third argument is a selection criterion that indicates which files, of all those that are currently open (by some user or by some subsystem), are to be included in the output $list. The following criteria are allowed:
| FILE=fid | include only files with filenames matching fid (wildcards allowed). |
|---|---|
| SUBSYS=subsysid | include only files opened by subsystem subsysid. Wildcards are allowed. |
| USER=usernum | include only files opened by user usernum. |
Actually, all files are always included in the output $list, but the excluded files have the high order bit of their file numbers turned on. This tells $StatLD to exclude the files from the difference $list.
Syntax
%result = $FiStatL(list_identifier, stat_list, criterion)
%result is either a positive number which is the milliseconds since the online was brought up, or it is a negative error code.
-3 - CCATEMP is full -5 - Required parameter not specified -6 - Invalid $list identifier -12 - Invalid name in stat_list -13 - STAT not linked in -16 - Invalid selection criterion
$FiStatL return codes
The following program displays some statistics for all files.
