Typedefs | |
| typedef void(* | lwip_thread_fn )(void *arg) |
| Function prototype for thread functions. | |
Functions | |
| err_t | sys_mutex_new (sys_mutex_t *mutex) |
| Create a new mutex. | |
| void | sys_mutex_lock (sys_mutex_t *mutex) |
| Lock a mutex. | |
| void | sys_mutex_unlock (sys_mutex_t *mutex) |
| Unlock a mutex. | |
| void | sys_mutex_free (sys_mutex_t *mutex) |
| Delete a semaphore. | |
| int | sys_mutex_valid (sys_mutex_t *mutex) |
| Check if a mutex is valid/allocated: return 1 for valid, 0 for invalid. | |
| void | sys_mutex_set_invalid (sys_mutex_t *mutex) |
| Set a mutex invalid so that sys_mutex_valid returns 0. | |
| err_t | sys_sem_new (sys_sem_t *sem, u8_t count) |
| Create a new semaphore. | |
| void | sys_sem_signal (sys_sem_t *sem) |
| Signals a semaphore. | |
| u32_t | sys_arch_sem_wait (sys_sem_t *sem, u32_t timeout) |
| Wait for a semaphore for the specified timeout. | |
| void | sys_sem_free (sys_sem_t *sem) |
| Delete a semaphore. | |
| int | sys_sem_valid (sys_sem_t *sem) |
| Check if a semaphore is valid/allocated: return 1 for valid, 0 for invalid. | |
| void | sys_sem_set_invalid (sys_sem_t *sem) |
| Set a semaphore invalid so that sys_sem_valid returns 0. | |
| void | sys_msleep (u32_t ms) |
| Sleep for specified number of ms. | |
| err_t | sys_mbox_new (sys_mbox_t *mbox, int size) |
| Create a new mbox of specified size. | |
| void | sys_mbox_post (sys_mbox_t *mbox, void *msg) |
| Post a message to an mbox - may not fail -> blocks if full, only used from tasks not from ISR. | |
| err_t | sys_mbox_trypost (sys_mbox_t *mbox, void *msg) |
| Try to post a message to an mbox - may fail if full or ISR. | |
| u32_t | sys_arch_mbox_fetch (sys_mbox_t *mbox, void **msg, u32_t timeout) |
| Wait for a new message to arrive in the mbox. | |
| u32_t | sys_arch_mbox_tryfetch (sys_mbox_t *mbox, void **msg) |
| Wait for a new message to arrive in the mbox. | |
| void | sys_mbox_free (sys_mbox_t *mbox) |
| Delete an mbox. | |
| int | sys_mbox_valid (sys_mbox_t *mbox) |
| Check if an mbox is valid/allocated: return 1 for valid, 0 for invalid. | |
| void | sys_mbox_set_invalid (sys_mbox_t *mbox) |
| Set an mbox invalid so that sys_mbox_valid returns 0. | |
| sys_thread_t | sys_thread_new (const char *name, lwip_thread_fn thread, void *arg, int stacksize, int prio) |
| The only thread function: Creates a new thread ATTENTION: although this function returns a value, it MUST NOT FAIL (ports have to assert this!) | |
| u32_t | sys_jiffies (void) |
| Ticks/jiffies since power up. | |
| u32_t | sys_now (void) |
| Returns the current time in milliseconds, may be the same as sys_jiffies or at least based on it. | |
