Once more a C approach wouldn't put any constructor/destructor pointers in a
structure without a good reason to do so, which I don't see in the previous
example if not to mimic a C++ pattern.

I would rather build a machinery to process with static field such as:

#define DATAFIELD_MAX 255

struct row
{
  void *prevrow;
  void *nextrow;
  int freechar;
  char datafield[DATAFIELD_MAX];
  int datatype;
};

struct table
{
  int nrow;
  struct *rowp;
};

struct table *insert(struct table *tab, char *data, size_t size);
struct table *remove(struct table *tab, char *data, size_t size);
int gettype(struct table *tab, char *data, size_t size);
char *getdata(struct table *tab, int type);
