^FILE_CLOSE_
This procedure closes an open file. The ^CLOSE and ^FILE_CLOSE_ procedures
function exactly the same. ^FILE_CLOSE_ may be called whether USCODE is
converted or unconverted. This procedure is a waited operation.
The syntax, condition code settings, and considerations regarding this procedure are
the same as the counterpart in the Guardian Procedure Calls Reference Manual.
^FILE_GETINFO_
This procedure obtains a limited set of information about a file identified by file number.
The ^FILE_GETINFO_ procedure provides only a subset (last error, file name, and file
type) of the functions available with ^FILEINFO. ^FILEINFO and ^FILE_GETINFO_
can be called whether the application is converted or unconverted. ^FILE_GETINFO_
is a waited operation.
Except for the following considerations, the syntax, condition code settings, and
considerations regarding this procedure are the same as the counterpart in the
Guardian Procedure Calls Reference Manual.
Considerations
•

current task.
0 The user exit or task is not to be restarted. Control is given back to the
calling process. This is the default.
