Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

#define INCL_DOSDEVIOCTL
 
USHORT DosDevIOCtl(psfFactors, 0L, 0x0066, 0x0007, hDevice)
PSCALEFACT psfFactors;    /* pointer to structure for scaling factors */
HFILE hDevice;            /* device handle                            */
 
The MOU_GETSCALEFACTORS function retrieves the scaling factors of the
current pointing device. Scaling factors are the ratio values that determine
how much relative movement is necessary before the mouse device driver
reports a pointing-device event. In graphics mode, this ratio is given in
mickeys-per-pel. In text mode, this ratio is given in mickeys-per-character.
The default values are one mickey-per-row and one mickey-per-column.
 
Parameter   Description
────────────────────────────────────────────────────────────────────────────
 
psfFactors  Points to the SCALEFACT structure that receives the scaling
            factors.
 
hDevice     Identifies the pointing device that receives the device-control
            function. The handle must have been created previously by using
            the DosOpen function.
 
Return Value
 
The return value is zero if the function is successful or an error value if
an error occurs.
