how to create dynaimc size of NULL pointers array ?

Clash Royale CLAN TAG#URR8PPPhow to create dynaimc size of NULL pointers array ?
i want to have dynamic size of array of pointers , how can i do it with malloc?
without malloc it look's like this :
typedef struct Nodes
{
UINT_64 Datasequence;
UINT_32 Data;
struct Nodes* next;
}Node;
Node * head_ri_interface[2][50] ;
wich wil give mi array of [2][50] of null pointers to uninitalized struct's .
i have triied to this this like this :
void NULLPointerArrayInit(int MAX_LIST_HEAD){
int i = 0 ;
for(i = 0; i < 2; i++)
{
head_ri_interface[i] = (Node *) malloc ( sizeof(Node *) * MAX_LIST_HEAD );
}
}
but i see that i get that the struct i am pointing at are not NULL . what am i doing wrong ?
head_ri_interface[i]

But
head_ri_interface[i]is an array of 50 pointers to your structure? Are you sure you want an array of arrays?– Some programmer dude
