No, he is defining a function 'makepoint' that returns a value of type 'struct point'. 'struct point' is presumably defined at some earlier point. (At a guess 'struct point' is defined as: struct point { int x; int y; }; Such a definition would at least be reasonable, and consistent wwith the usage of 'struct point' in the function 'makepoint') -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
