this should be simple

[bob]

Suppose I want to write a very simple Linux C program to detect that the user 
has pressed CTRL (or ALT) and PGUP.

How do I do this?

I remember back to my QNX days that there were term functions which could 
detect this but for the life of me I can't find the Linux equivalent.

Thanks.

PS.
I actually want to do this under ncurses ... but for now I can't even do it 
on a text console with straight forward calls to getchar().
