Updates the display of the VIO presentation space.

Syntax

VioShowPS (Depth, Width, Cell, hvps)

Parameters

Depth (ULONG) - input: Depth:The depth of the updated rectangle.
Width (ULONG) - input: Width:The width of the updated rectangle.
Cell (ULONG) - input: Offset to first updated cell:The offset to the first updated cell. The offset of the top-left corner is zero.
hvps (HVIO) - input: VIO presentation handle:VIO presentation space handle. This is either zero to indicate the default VIO session or a value returned by VioCreatePS.

Return Code

rc (APIRET) - returns

Return code descriptions are:

0 NO_ERROR
421 ERROR_VIO_INVALID_PARMS
436 ERROR_VIO_INVALID_HANDLE

Remarks

This call is used to specify that part or all of the presentation space the logical buffer needs to be redrawn.

This call has the same function as VioShowBuf, but the area to update is specified differently.
