i get all what you said ,and do my program like bellow .but it doesn't work
well, i wonder if ther is some other mistaken ,please help!
record struct :
{
Uint32 id;
float hh;
char[10] info1;
char[20] info2;
} myrecord;
my section getting data:
char * pBuffer;
DWORD * temp,temp1;
pBuffer=(char *) rInfo.m_pBytes;
temp=(DWORD*)pBuffer;
temp1=*temp;
*(DWORD*)&temRec.id=SyncHHToHostDWord(temp1);// here i get id which is
dword
pBuffer+=sizeof(DWORD);
temp=(DWORD*)pBuffer;
temp1=*temp;
*(float*)&temRec.hh=SyncHHToHostDWord(temp1);// here i get hh which is
float pBuffer+=sizeof(float);
char *tt;
long re;
re=GetString( tt,pBuffer,strlen(pBuffer));
temRec.info1=tt; //here i get info1
pBuffer+=re;
re=GetString(tt,pBuffer,strlen(pBuffer));
temRec.info2=tt;// here i get info2
long GetString(char * pdest,char* psrc,int len) //my function of getting
string
{
int off=0;
while ((*psrc!='\0'))
{
*pdest=*psrc;
*pdes++;*psrc++;
off++;
}
*pdest='\0';
return strlen(pdest);
}
