assignment from incompatible pointer type
I have set up the following struct:
typedef struct _thread_node_t {
pthread_t thread;
struct thread_node_t *next;
} thread_node_t;
... and then I have defined:
// create thread to for incoming connection
thread_node_t *thread_node = (thread_node_t*) malloc(sizeof(thread_node_t));
pthread_create(&(thread_node->thread), NULL, clie开发者_运维问答nt_thread, &csFD);
thread_node->next = thread_arr; // assignment from incompatible pointer type
thread_arr = thread_node;
where thread_arr is thread_node_t *thread_arr = NULL;
I don't understand why the compiler is complaining. Maybe I'm misunderstanding something.
Shouldn't struct thread_node_t *next;
be struct _thread_node_t *next;
Also, do away with the explicit cast.
thread_node_t *thread_node = (thread_node_t*) malloc(sizeof(thread_node_t));
to
thread_node_t *thread_node = malloc(sizeof(thread_node_t));
It's because thread_arr is a thread_node_t pointer, and your next member is a struct thread_node_t pointer. Not the same thing.
