Removing the typedefs will still cause compilation to error out not knowing
what a is. For example:
// Forward declaration
struct a;
// Pointer to function with struct as parameter
typedef int (*FxnPointer)(a* WontComplie);
// Actual declaration of struct with function pointer type declared above.
struct _a
{
int foo;
int bar;
FxnPointer PtrToFxn;
} a;
int main(void)
{
return 0;
}
Resutls are :
FxnPtrEx.c:5:28: error: expected ‘)’ before ‘*’ token
FxnPtrEx.c:12:2: error: expected specifier-qualifier-list before ‘FxnPointer’
It seems to not take the forward declaration of the struct as a member of the
parameter list of the FxnPointer type, unless I am missing something here.
What I am trying to do is create a function pointer that takes in as a
parameter a pointer to a structure, but in that structure is a function pointer
of that type. I am confused as to why the forward declaration is not working
here.
