Assuming the node structure as follows:

typedef struct node{
      int val;
      struct node *children[m];
}NODE;

-------------------------
void mDFS(NODE *t){
    NODE *p = NULL;
    int i;
    if(t == NULL) return;

    push(Stack, t);

    while(!empty(Stack)){
        p = pop(Stack);
        print p->val;
        
        for(i = m-1; i >=0; i--){
             if(p->children[i]) push(Stack, p->children[i])
        }
    }
}

Hmm, the question says "without using extra memory", is the usage of stack account for extra memory?!
Even I don't know how to do this without stack!

typedef struct
{
Node *top;
}STACK;
or
typedef struct

Node ST[maxsize];
int stack_pointer;
}STACK;
