#define LWIP_COMPAT_MUTEX 0 |
Define LWIP_COMPAT_MUTEX if the port has no mutexes and binary semaphores should be used instead
#define SYS_ARCH_TIMEOUT 0xffffffffUL |
Return code for timeouts from sys_arch_mbox_fetch and sys_arch_sem_wait
#define SYS_MBOX_EMPTY SYS_ARCH_TIMEOUT |
sys_mbox_tryfetch() returns SYS_MBOX_EMPTY if appropriate. For now we use the same magic value, but we allow this to change in future.
#define sys_mbox_set_invalid_val | ( | mbox | ) | sys_mbox_set_invalid(&(mbox)) |
Same as sys_mbox_set_invalid() but taking a value, not a pointer
#define sys_mbox_tryfetch | ( | mbox, | |
msg | |||
) | sys_arch_mbox_tryfetch(mbox, msg) |
For now, we map straight to sys_arch implementation.
#define sys_mbox_valid_val | ( | mbox | ) | sys_mbox_valid(&(mbox)) |
Same as sys_mbox_valid() but taking a value, not a pointer
#define sys_sem_set_invalid_val | ( | sem | ) | sys_sem_set_invalid(&(sem)) |
Same as sys_sem_set_invalid() but taking a value, not a pointer
#define sys_sem_valid_val | ( | sem | ) | sys_sem_valid(&(sem)) |
Same as sys_sem_valid() but taking a value, not a pointer
#define sys_sem_wait | ( | sem | ) | sys_arch_sem_wait(sem, 0) |
Wait for a semaphore - forever/no timeout
typedef void(* lwip_thread_fn) (void *arg) |
Function prototype for thread functions
u32_t sys_jiffies | ( | void | ) |
Ticks/jiffies since power up.
