prototypes for passing custom types

i have a function that accepts a custom type as an input, but when i prototyped it eg: void myfunction(mytype); i get Error: parameter list is out of context, however c++ will compile it like this, i have another function that accepts both my custom type and an int, but if i include the int in the prototype c++ gives the error 'int ' : prototype parameter in name list illegal, without it will c compile under c++, my other c compiler Digital Mars C compiler gives error with both,

anyone got any ideas??

thanks in advance

Trying to understand your post, it sounds like you're using a struct or something similar. Here's the thing, C and C++ are not the same, they never will be. For example:

Code:

---

struct name{
  /* Data members */
};
.
.
.
void function ( name t ); /* Works with C++, not with C */
void function ( struct name t ); /* Works with C and C++ */

---

C requires the use of the struct tag while C++ makes it optional. Such is the way with user defined types, if your type is a struct then add the struct keyword wherever you instance it and it should compile. Another way is to typedef the struct and use the typedef'd name:

Code:

---

typedef struct name{
  /* Data members */
} NAME;
.
.
.
void function ( NAME t ); /* Works with C and C++ */

---

-Prelude

i have done it the 2nd way with the typedef, and i get the errors defined above, i am writing it all in c, but using the visual c++ compiler/ide then compiling it with my other c compiler

Please post some code then

-Prelude

i solved it, i keep all the prototypes in a separte header file, and i was including that before i created my typedef structure, so it wasent recognising it,

thanks for ur help anyway
