QNX Thread 生命周期解释

 

 

 

 

STATE_CONDVAR
　　The thread is blocked on a condition variable (e.g., it called pthread_cond_wait()).
STATE_DEAD
　　The thread has terminated and is waiting for a join by another thread.
STATE_INTR
　　The thread is blocked waiting for an interrupt (i.e., it called InterruptWait()).
STATE_JOIN
　　The thread is blocked waiting to join another thread(e.g., it called pthread_join()).
STATE_MUTEX
　　The thread is blocked on a mutual exclusion lock (e.g., it called pthread_mutex_lock()).
STATE_NANOSLEEP
　　The thread is sleeping for a short time interval (e.g., it called nanosleep()).
STATE_NET_REPLY
　　The thread is waiting for a reply to be delivered across the network (i.e., it called MsgReply*()).
STATE_NET_SEND
　　The thread is waiting for a pulse or signal to be delivered across the network (i.e., it called MsgSendPulse(), MsgDeliverEvent(),or SignalKill()).
STATE_READY
　　The thread is waiting to be executed while the processor executesanother thread of equal or higher priority.
STATE_RECEIVE
　　The thread is blocked on a message receive (e.g., it called MsgReceive()).
STATE_REPLY
　　The thread is blocked on a message reply (i.e., it called MsgSend(),and the server received the message).
STATE_RUNNING
　　The thread is being executed by a processor.The kernel uses an array (with one entry per processor in the system) tokeep track of the running threads.
STATE_SEM
　　The thread is waiting for a semaphore to be posted (i.e., it called SyncSemWait()).
STATE_SEND
　　The thread is blocked on a message send (e.g., it called MsgSend(),but the server hasn't yet received the message).
STATE_SIGSUSPEND
　　The thread is blocked waiting for a signal (i.e., it called sigsuspend()).
STATE_SIGWAITINFO
　　The thread is blocked waiting for a signal (i.e., it called sigwaitinfo()).
STATE_STACK
　　The thread is waiting for the virtual address space tobe allocated for the thread's stack (parent will have called ThreadCreate()).
STATE_STACK
　　The thread is waiting for the virtual address space tobe allocated for the thread's stack (parent will have called ThreadCreate()).
STATE_STOPPED
　　The thread is blocked waiting for a SIGCONT signal.
STATE_WAITCTX
The thread is waiting for a noninteger (e.g., floating point) context to become available for use.
STATE_WAITPAGE
The thread is waiting for physical memory to beallocated for a virtual address.
STATE_WAITTHREAD
The thread is waiting for a child thread to finishcreating itself (i.e., it called ThreadCreate()).
In discussion and in the documentation, we usually omit the “STATE_” prefix.
