Can't be done, in general. In particular function pointers in C have
no analogue in standard Pascal because there is no such thing as a
procedure variable in Pascal. Wirth did add procedure variables to
Modula-2, and Turbo Pascal has them as well. Lot sof other aspects of
C, such as the ... ? ... : ... if operator and the passing of
strcutured objects to prodcedures would be pretty hard too.
