No, no, no.  You're missing the whole point.  I am creating a function vector
table (list of conditions and the function that should be called when the
condition is met).  I need to install pointers to all sorts of functions into
this list.  So to be more specific:

InstallAction("print",print);
InstallAction("remove",remove);

is closer to the call that I want to make.  But I still want the version of 
print that takes a char* argument.   All I really want is a pointer to this
damned function.  Isn't there a well defined way of doing this?
