共享存储区：先获取共享区，KEY为75，并获得描述符，然后将该共享存储区附接到addr这个虚拟地址上，如消息队列类似，利用while循环从10到1打印输出，并将i值赋给addr。在SERVER中，创建共享存储区，并将起始地址也设置为addr，服务进程共享存储区，所以直接用while循环输出打印“receive”。-ON划词翻译ON实时翻译



Shared memory: first get sharing area, 75 for KEY, and obtain the descr iptor, then the shared memory attached to the addr this virtual address, such as the message queue is similar, using the while loop　10 to 1 print output, and the I value is assigned to addr. In SERVER, create a shared memory area, and the starting address is set to addr, the service process shared memory, so the direct use of while loop output print　receive .
