Struct and Pointer Segmentation Error in C

Question

can anyone help with this segmentation error i keep getting. this code is simple but the error is so hard to figure out.

struct Link {
  int key;
  unsigned dat         


        

Answer 1

The part (and everywhere &l is used)

if (!srt)
    return &l;

is returning the address of a stack variable. Your addInOrder function should probably have the signature

struct Link* addInOrder(struct Link* srt, struct Link* l);
