如何赋值给结构体变量?

[xhwu3721]

如下:
typedef struct
{
PortAddrTable SrcPort;
PortAddrTable DstPort;
}PairsPort;
PairsPort PairsPortList[40];
typedef struct
{
int iPort;
int iHub;
int iSlot;
int ucSrcMAC[6];
int ucDstMAC[6];
}PortAddrTable;

我通过函数这样赋值给它,怎么不行呢?
int LoadConfigFile()
{
char temp[30],sect[3],stmp[3];
memset(temp,0,sizeof(temp));
memset(sect,0,sizeof(sect));
memset(stmp,0,sizeof(stmp));
int i=0;
for(i=0;i<2;i++)
{
SetPortId(temp,PairsPortList[i]);
}
return 1;
}
int SetPortId(char buffer[],PairsPort Port)
{

Port.SrcPort.iHub=5;
Port.SrcPort.iSlot=6;
Port.SrcPort..iPort=7;

Port.DstPort.iHub=5;
Port.DstPort.iSlot=6;
Port.DstPort..iPort=7;

return 1;
}
为什么我得到的值始终为:
PairsPortList[0].SrcPort.iHub=0;
PairsPortList[0].SrcPort.iSlot=0;
PairsPortList[0].SrcPort.iPort=0;

PairsPortList[1].DstPort.iHub=0;
PairsPortList[1].DstPort.iSlot=0;
PairsPortList[1].DstPort.iPort=0;
是我传递的参数不对吗?

[zhujianping_es]

int SetPortId(char buffer[],PairsPort Port)
{

Port.SrcPort.iHub=5;
Port.SrcPort.iSlot=6;
Port.SrcPort..iPort=7;

Port.DstPort.iHub=5;
Port.DstPort.iSlot=6;
Port.DstPort..iPort=7;

return 1;
}
This is call by value.PairsPort Port is not moidfied !
You should call it by address or referrence!
like:
int SetPortId(char buffer[],PairsPort *Port)
int SetPortId(char buffer[],PairsPort &Port)

传入的结构如果想给它值且要回用的话,
可以用引用和地址,但不能传一个临时的拷
