Lines: 26 I have a question regarding pointers to structures and their use in data structure definitions found in #include files. Suppose I wish to declare a commonly used data structure, which has as one of its fields a pointer to a less often used structure. I wish to define the structure "templates" in different #include files: foo.h: bar.h: struct bar; struct bar { ... struct foo { }; ... struct bar *f_b; }; Is it alright to #include "foo.h" and not "bar.h" in a source file if the fields of "struct bar" are not used? I would think that it would be fine as long as pointers to structs are all the same "flavor". The compiler I'm using doesn't mind. I suppose I could #include both if I had to, but I'd rather not because of modularity reasons. I'm just wondering what the usual practice is. -- Andrew Scott andrew@teletron.uucp - or - {att, ubc-cs, watmath, ..}!alberta!teletron!andrew
