	In a program I am writing I have several versions of a
particular function and I intend to allow the user to select which is
used at run time. To do this I aim to have a "dummy" function which I
will set "equal" to the appropriate function when the user makes his
choice. The rest of my program will then call this "dummy" function -
and hence the correct "real" function - whenever necessary. How do I
declare and assign to this dummy function? I am using the cc compiler
under Sun-OS 4.1. Thanks,

			Geoff.
