#define INCL_GPICONTROL
 
BOOL GpiResetPS(hps, flOption)
HPS hps;           /* presentation-space handle */
ULONG flOption;    /* reset option              */
 
The GpiResetPS function resets the presentation space. In general, resetting
the presentation space restores attributes to their default values──that is,
the values given to the attributes when the presentation space was created
or the values specified in the last call to the GpiSetDefAttrs function. The
function can reset the presentation space in three ways: as if a segment
were closed; as if the presentation space had just been created, but without
deleting any resources; and as if the presentation space had just been
created. It uses the flOption parameter to determine how to reset the
presentation space.
 
The GpiResetPS function does not draw or erase the device. It is up to the
application to erase the screen, if this is required. Also, the function
does not affect the association between the specified presentation space and
a device context.
 
The GpiResetPS function also deselects a bitmap if any are selected into a
memory device context.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
hps        Identifies the presentation space.
 
flOption   Specifies the reset option. It can be one of the following:
 
           Value          Meaning
           ─────────────────────────────────────────────────────────────────
           GRES_ATTRS     Sets all current attributes to their default
                          values, the current model transform to unity, and
                          the current position to (0,0). The option also
                          ends any open path, area, or element brackets and
                          closes any open segment. Finally, it sets the
                          current clip path and viewing limits to their
                          widest possible values.
 
           GRES_SEGMENTS  Resets as described for GRES_ATTRS, plus it
                          deletes all retained segments, clears any boundary
                          data, releases the clip region (if any), enables
                          kerning (if the device supports it), and sets the
                          default values for initial segment attributes,
                          default viewing transform, graphics field, drawing
                          mode, draw controls, edit mode, and attribute
                          mode.
 
           GRES_ALL       Resets as described for GRES_ATTRS and
                          GRES_SEGMENTS, plus it deletes any logical fonts
                          and local identifiers for bitmaps and sets the
                          logical color table to its default value.
 
Return Value
 
The return value is GPI_OK if the function is successful or GPI_ERROR if an
error occurred.
 
Errors
 
Use the WinGetLastError function to retrieve the error value, which may be
one of the following:
 
     PMERR_INV_HPS
     PMERR_INV_RESET_OPTIONS
     PMERR_PS_BUSY
