passing structs as arguements

Ok well, I know that passing structs as arguements is slow, and uses up alot of stack space, but what about passing pointers to structs, is there any real speed or memory penalties to passing pointers to structs, I would think not since a pointer is just a 32bit long.

You can also pass the struct/class by reference. Make it const if it's not being modified, of course.

you are correct!

the best way to emulate passing the struct without the stack allocation penalty is:

struct somestruct{int someint;int someotherint;char somechararray[128];};int DoSomething(const somestruct& SomeStruct){printf("%s\n",Somestruct.somechararray);return SomeStruct.someint;}somestruct someStruct;DoSomething(SomeStruct);

You get the drill. [smile]
