LWIP_NETCONN_FULLDUPLEX==1: Enable code that allows reading from one thread, writing from a 2nd thread and closing from a 3rd thread at the same time. ATTENTION: This is currently really alpha! Some requirements:
- LWIP_NETCONN_SEM_PER_THREAD==1 is required to use one socket/netconn from multiple threads at once
- sys_mbox_free() has to unblock receive tasks waiting on recvmbox/acceptmbox and prevent a task pending on this during/after deletion
| #define LWIP_NETCONN_SEM_PER_THREAD 0 |
LWIP_NETCONN_SEM_PER_THREAD==1: Use one (thread-local) semaphore per thread calling socket/netconn functions instead of allocating one semaphore per netconn (and per select etc.) ATTENTION: a thread-local semaphore for API calls is needed:
- LWIP_NETCONN_THREAD_SEM_GET() returning a sys_sem_t*
- LWIP_NETCONN_THREAD_SEM_ALLOC() creating the semaphore
- LWIP_NETCONN_THREAD_SEM_FREE() freeing the semaphore The latter 2 can be invoked up by calling netconn_thread_init()/netconn_thread_cleanup(). Ports may call these for threads created with sys_thread_new().
