STL容器[34]

 

SERVER以读打开FIFO；

CLIENT以写打开FIFO；

SERVER关闭FIFO；

CLIENT向当前FIFO写数据，此时CLIENT获得一个SIGPIPE信号。如果忽略该信号，那么write将返回-1，ERRNO为EPIPE

 

向一个写打开，当对端已经关闭的

 

 

void doPIPE (int a)

{

std::cout << "A:" << a << std::endl;

}

 

int main()

{

std::cout << "PIPE_BUF:"    << PIPE_BUF << std::endl;

 

struct sigaction sig;

sigemptyset(&sig.sa_mask);

sig.sa_handler = doPIPE;

        sig.sa_flags = 0;

        sigaction(SIGPIPE, &sig, NULL);

 

MT_Fifo c2s;

 

c2s.open(C2S_FIFO, MT_Fifo::EM_WRITE);

 

std::cout << "c2s fd:" << c2s.fd() << std::endl;

 

sleep(10);

std::cout << "To Send:" << std::endl;

int iRet = c2s.write(" ", 1);

std::cout << "Ret:" << iRet << "|Errno:" << errno << "|" << strerror(errno) << std::endl;

 

return 0;
