server端主函数

while(1)

	{

	    int ret;

		Gate *clt=(Gate *)calloc(1, sizeof(Gate));

		memset(Recv_Buf,0,sizeof(Recv_Buf));

		ret=recv(sClinetSock,Recv_Buf,sizeof(Recv_Buf),0);

		printf("Recv_Buf Mesg:%s\n",Recv_Buf);

		ret=sizeof(Gate);

		printf("sizeof(Gate):%d\n",ret);

		sscanf(Recv_Buf,"%d%d%lf%lf%lf",&clt->tx_wave,&clt->gate_length,&clt->gate_length1,&clt->gate_length2,&clt->start_time);

		printf("Packet Report: \ntx_wave = %d\n gate_length = %d\n gate_length1 = %f\ngate_length2 = %f\nOPNET Time = %f\n", clt->tx_wave,clt->gate_length,clt->gate_length1,clt->gate_length2,clt->start_time);

		

		int message_size = sizeof(Gate);

		clt->tx_wave = clt->tx_wave + 2;

		memset(Send_Buf,0,sizeof(Send_Buf));

	    sprintf(Send_Buf,"%d %d %f %f %f",clt->tx_wave,clt-> gate_length,clt-> gate_length1,clt-> gate_length2,clt->start_time);

	    printf("Send_Buf Mesg:%s\n",Send_Buf);

	    send(sClinetSock,Send_Buf,sizeof(Send_Buf),0);

		free(clt);

		

	}

client端主函数

while(1)

	{

	Esa_Execute_Until(esa_handle, &status_1, time_val, exec_options, &time_reached, &num_events);

	recv(sClntSock,RSC_Buf,sizeof(RSC_Buf),0);

    printf("RSC_Buf Mesg:%s\n",RSC_Buf);

	Interface_Packet_Data *clt=(Interface_Packet_Data *)calloc(1, sizeof(Interface_Packet_Data));

	sscanf(RSC_Buf,"%d%d%lf%lf%lf",&clt->tx_wave,&clt->gate_length,&clt->gate_length1,&clt->gate_length2,&clt->start_time);

    printf("收到的数据包为: \ntx_wave = %d\n gate_length = %d\n gate_length1 = %f\ngate_length2 = %f\nOPNET Time = %f\n", clt->tx_wave,clt->gate_length,clt->gate_length1,clt->gate_length2,clt->start_time);

	

}

client端发送5个结构体给server。server更改结构体中yppe值后再返回给client，但是接收完后，程序好像处于奔溃，结果如下
