Multiple Keyboard presses?

In nehe's tuts they describe a way to check if more than one key is pressed at once.
How do i make this in linux?
If i press up and left at the same time it will just go left.. =(

I use the SDL library for nice input stuff (joysticks, mice, keyboard). Maybe it will help you too: www.libsdl.org (http://www.libsdl.org)

One way to perform it, it's to used the glut key up function. You just have a global variable for each key you want to press. If the event key down is activated, change the state of the variable to press and perform the action into a idle function. When you detect the key is up, re-change the state to un-activated.

Hope it's help.

GL has its own keyboard function, one called when a key is pushed, one called when a key is released (Same name with "Up" in addition).

Just keep in memory if your left/right/... keys are is pushed staight or not.
