Warn if another typedef'd name of a type is used in an argument list

Question

Consider a large project, where many types are typedef\'d, e.g.

typedef int age;
typedef int height;

and some functions gettin

Answer 1

As others already stated, there is no support for this in C. If you absolutely want strong type checking to happen, you could do like this:

typedef struct {int a;} age;
typedef struct {int h;} height;

void printPerson(age a, height h)
{
    printf("Age %d, height %d\n", a.a, h.h);
}

age a = {30};
height h = {180};

printPerson(h, a);  // will generate errors

Beware that this might have some performance impact, though.
