An array of function pointers.

[John Antypas]

This may seem like a simple question but I've no luck with an answer so 
perhaps the net could help.  

In a graphics application we're writing at work, we have several functions for 
drawing lines, circles etc.  We'd like to set up something like a vector table.
If the vector table has a NULL in a spot, then the interpreter will use its
internal routines instead of faster device specific code.  As an example:

vectors[] =	{ dev_line(),
		  dev_box(),
		  dev_circle(),
		  dev_arc(),
		  dev_text()
		}

This says we have device specific code for all five functions.  Yet when I 
try to copy function addresses, the compiler complains.  How do I get the
address of a funciton and put it into an array for calling later?

Thanks.
