C - byte array to structure (dns query)

Question

I have these structures:

typedef struct dnsQuery {
  char header[12];
  struct TdnsQuerySection *querySection;
} TdnsQuery;

typedef struct dnsQuerySection {
  u         


        

Answer 1

your query section printer is an incomplete type. you need to either typedef it beforehand and not use the structure keyword or use the structure name rather than the typedef. e.g.:

typedef struct foo Foo;

struct {
    Foo* querySection;
    // effectively same as above
    struct foo* querySection2;

    // NOT the following. 
    struct Foo* querySectionWrong; 
};
