Question

Given:

struct objStruct {
    int id;
    int value;
};

typedef struct objStruct Object;

Is there a shortcut to allocate and initialize the object, something like a C++ constructor?
It could even be a preprocessor macro. Whatever makes the code shorter and more readable than this:

Object *newObj = malloc(sizeof(Object));
// successful allocation test snipped
newObj->id = id++;
newObj->value = myValue;

Answer 1

In C I typically create a function in the style of a constructor which does this. For example (error checking omitted for brevity)

Object* Object_new(int id, int value) { 
  Object* p = malloc(sizeof(Object));
  p->id = id;
  p->value = value;
  return p;
}

...
Object* p1 = Object_new(id++, myValue);
