This is part of Family API which allow to create dual-os version of program runs under OS/2 and DOS

Note: This is legacy API call. It is recommended to use 32-bit equivalent

VioSetCurType

This call sets the cursor type.

Syntax

VioSetCurType (CursorData, VioHandle)

Parameters

CursorData (PVIOCURSORINFO) - input : Address of the cursor characteristics structure:

startline (USHORT) : Horizontal scan line in the character cell that marks the top line of the cursor. If the character cell has n scan lines, 0 is the top scan line of the character cell and (n - 1) is the bottom scan line.

endline (USHORT) : Horizontal scan line in the character cell that marks the bottom line of the cursor. Scan lines within a character cell are numbered as defined in startline. The maximum value allowed is 31.

cursorwidth (USHORT) : Width of the cursor. In text modes, cursorwidth is the number of columns. The maximum number supported by the OS/2 base video subsystem is 1. In graphics modes, cursorwidth is the number of pels.

A value of 0 specifies the default width. In text modes, this is 1 column. In graphics modes, this is the number of pels equivalent to the width of one character.

cursorattrib (USHORT) : A value of -1 denotes a hidden cursor, all other values denote a normal cursor.

VioHandle (HVIO) - input : This must be zero unless the caller is a Presentation Manager application, in which case it must be the value returned by VioGetPs.

Return Code

rc (USHORT) - return

Return code descriptions are:

0 NO_ERROR

355 ERROR_VIO_MODE

356 ERROR_VIO_WIDTH

421 ERROR_VIO_INVALID_PARMS

436 ERROR_VIO_INVALID_HANDLE

465 ERROR_VIO_DETACHED
