We have a dictionary type which accepts a callback function for freeing
the elements of the dictionary when an entry is deleted or the complete
dictionary is freed.

The dictionary always stores strings per definition.

When using the dictionary each application must define the same standard
callback function.

It would be much easier if a standard callback function would
be available (like it is for all list types).

This is the function working when strings are allocated on heap:

void drmaa2_dict_string_free(char** key, char** value)
{
       drmaa2_string_free(key);
       drmaa2_string_free(value);
    }

drmaa2_dict dict = drmaa2_dict_create((drmaa2_dict_entryfree)drmaa2_dict_string_free);

if (drmaa2_dict_set(dict, strdup("key"), strdup("value")) != DRMAA2_SUCCESS) {
       printf("Error: Could not set a new value in the dictionary.\n");
       return;
    }

if (drmaa2_dict_set(dict, strdup("key2"), strdup("")) != DRMAA2_SUCCESS) {
       printf("Error: Could not set a new value in the dictionary.\n");
       return;
    }

/* Frees strings implicitly. */
    drmaa2_dict_free(&dict);
