How do I check if the mouse wheel is being rotated?

dbMouseclick() doesn't seem to have the ability.

Quote: "
dbMouseClick
This command will return a value if a mouse button is pressed. The integer return value will depend on which mouse button has been pressed. A mouse can have up to four buttons, and each one can be detected using this command. Each button is assigned a value. The left button is assigned a value of 1. The right button is assigned a value of 2. Buttons three and four are assigned values of 4 and 8 respectively. When more than one button is pressed, the value of the buttons are added to produce a combined value you can check for.

Syntax
int dbMouseClick ( void ) "

Not correct. The mouse wheel is read as the Z-position of the mouse. Button 3 is a button or it may represent the mouse wheel being pressed if that feature exists. But it doesn't reflect the wheel rotating.

My mouse at home has two extra buttons on the sides of the mouse that represent buttons 3 and 4.

if (dbMouseClick() == 1) - LMB
if (dbMouseClick() == 2) - RMB
if (dbMouseClick() == 3) - LMB + RMB

dbMouseMoveZ() is a scroll wheel as far as I know.

I remember having problems with this little bugger. I had to:

int mmz = dbMouseMoveZ();

to make it work.

dbMouseMoveZ() and dbMouseZ() return the movement and position of the scroll wheel in intervals of 120

Jonas is right. Also, rather than just using dbMouseMoveZ( ) in your loop, make sure you store it in a variable at the beginning of the loop then use that variable instead, because dbMouseMoveZ( ) can only be called once per loop. Also make the variable a float, so you can divide the value if you want because 120 seems a little big for most uses.
