Exporting functions (for use in other applications)

Hello,

sorry for bothering you another time. :-) There is another thing I cannot find 
a solution for..

Is it possible to export a function for use in another application? I have 
some huge functions in maxima that I need in another application. And if 
possible I wouldn't want to have to type them in myself.

Strictly speaking I'd like to export a function as C code.

If I have: f(x)=x^2; in maxima,
I'd like to get something like: double f(x) { return pow(x,2); }

I have found the save() function, but that saves the function in some for me 
rather hard to parse format.

Is there some other/better way to do what I need?

thanks again,
Max
