c - Malloc struct with double pointer -

i have structure looks this:

typedef struct{     char* name;     int count;     node **subnodes; }node; 

i receive name , count on network 1 one whole k-ary tree , reconstruct tree. how malloc struct?

node *n = null; fun(n, buf); //call function fun  void fun(node *n, void *buf){     //successfully extracted name , count buf     // count 5, i.e. node should have 5 subnodes ,      // name root     n = malloc(sizeof(*n)+strlen(name));     n->name = name;     n->count = count;     for(int i=0; i<n->count;i++)          fun(n->subnodes[i], buf+some_increment); } 

this crashes call fun second time. how should malloc properly? should malloc-ing each subnode?

first off, realise leaky? n on stack - aren't returning or "saving" value give anywhere permanently.

then haven't allocated memory subnodes, indexing reading unallocated memory.

without more complete example hard further, @ minimum need malloc subnodes.
