JRTP 服务端 怎么设置为堵塞模式啊？

[cauthy628]

求助老手，我起了个线程在死循环里面执行
do{

#ifndef RTP_SUPPORT_THREAD
error_status = sess_client.Poll();
checkerror(error_status);
#endif // RTP_SUPPORT_THREAD
sess_client.BeginDataAccess();

// check incoming packets
if (sess_client.GotoFirstSourceWithData())
{
printf("Begin play\n");
do
{
RTPPacket *pack;

while ((pack = sess_client.GetNextPacket()) != NULL)
{
// You can examine the data here
printf("Got packet !\n");


timestamp1 = pack->GetTimestamp();
lengh=pack->GetPayloadLength();
RawData=pack->GetPayloadData(); //得到数据

printf(" timestamp: %d lengh=%d\n",timestamp1,lengh);
// we don't longer need the packet, so
// we'll delete it

//Begin play
int fd = open("/dev/dsp", O_RDWR);
int status = write(fd, RawData,lengh );
printf("Play bytes:%d\n",status);
if (status != lengh)
perror("wrote wrong number of bytes");

status = ioctl(fd, SOUND_PCM_SYNC, 0);
if (status == -1)
perror("SOUND_PCM_SYNC ioctl failed");
printf("Play end\n");
close(fd);
sess_client.DeletePacket(pack);

}
} while (sess_client.GotoNextSourceWithData());
//return 0;

}

sess_client.EndDataAccess();


}while(1);

结果CPU 99%，请问JRTP里面的怎么设置堵塞模式的啊？

加Sleep降低CPU
