FSRNIT GDDM V3R2 Base Application Programming Reference SC33-0868-02 |
|
Function To reinitialize GDDM. FSRNIT Parameters None. Description Reinitializes GDDM. This function is equivalent to the FSTERM call followed by FSINIT. GDDM retains only information about the primary device. Do not use in association with GDDM-PGF; refer to the CHRNIT call description in the GDDM-PGF Programming Reference book. FSRNIT can be used as a more efficient alternative to FSTERM and FSINIT, where it is required to restart GDDM with no memory of any previously defined pages, symbol sets, and so on, but where the same primary device is to be retained. FSRNIT reinitializes the primary device (whether explicitly opened, or opened by default), and closes all other currently-open devices. After the FSRNIT call has been processed, the primary device will be available as the subject of a DSUSE. It is not actually in use (although, as always, an implicit DSUSE call is issued against the default primary device if necessary). If operator windows are being used by this instance of GDDM, a call to FSRNIT may cause them to be deleted. If an operator window that is associated with a virtual device in another instance of GDDM is deleted, the results of subsequent operations on that virtual device are undefined (see WSDEL). Note: FSRNIT does not reinitialize the presentation graphics routines of GDDM-PGF. If GDDM-PGF is being used, issuing a call to FSRNIT produces unpredictable results. Principal errors None. |
