GetControl32BitMaximum

Obtains the maximum setting of a control.

pascal SInt32 GetControl32BitMaximum (
                     ControlHandle theControl);
theControl
A value of type ControlHandle . Pass a handle to the control whose maximum setting you wish to obtain.
function result
A signed 32-bit integer equal to the maximum setting of the control.

DISCUSSION

Your application may use the GetControl32BitMaximum function to obtain a 32-bit value previously set with the function SetControl32BitMaximum .


SPECIAL CONSIDERATIONS

If your application uses a 32-bit control maximum value, it should not attempt to obtain this value by calling the pre-Mac OS 8.5 function GetControlMaximum or by accessing the contrlMax field of the ControlRecord structure, because the stored 16-bit value will not accurately reflect the current 32-bit control value.


VERSION NOTES

Available with Mac OS 8.5 and later.
