this is how i do it:
--
myHeader.h
#ifndef _myHeader
#define _myHeader
typedef struct
{
int a;
} MyStruct, *MyStructPtr;
extern void myFunction(MyStruct);
#endif // myHeader
--
*every* file includes this file - and the function is being
declared external, so it is up to the linked to sort that out,
not the compiler.
the reason for putting the "#ifndef" in there is to prevent
the compiler redefining the structure again (it is ok to define
the prototypes again).
if this is what you are after.. it works for me. of course my
situation differs as i have a large number of sub files
(components in my system) - that have their own header files.
in that case the main header file is generated by using a load
of #include's - which does the same thing.
hope this helps.
az.
