library function attempts to get the address of a thread's data block (by calling TlsGetValue).Assume that the returnNULL as the address of the Tiddata block. The calling thread does not have a tiddata block associated with that address. At this point, the C/C + + run-time library function allocates a tiddata block to the calling thread in the field and initializes it. The Tiddata block (via TlsSetValue) is then associated with the line threads. # # # #_beginthreadex相相应的推出函数是_endthreadex, this
