BOOL GpiQueryDefArcParams(hps, parcp)
HPS hps;             /* presentation-space handle               */
PARCPARAMS parcp;    /* pointer to structure for arc parameters */
 
The GpiQueryDefArcParams function retrieves the default arc parameters. The
default arc parameters define the values given to the arc parameters of a
presentation space whenever that presentation space is reset. (The arc
parameters define the shape and orientation of the ellipses drawn using the
arc functions.) A presentation space can be reset by using the GpiResetPS
function.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
hps        Identifies the presentation space.
 
parcp      Points to the ARCPARAMS structure that receives the arc
           parameters.
 
Return Value
 
The return value is GPI_OK if the function is successful or GPI_ERROR if an
error occurs.
 
Errors
 
Use the WinGetLastError function to retrieve the error value, which may be
one of the following:
 
     PMERR_INV_COORDINATE
     PMERR_INV_HPS
     PMERR_PS_BUSY
