memcpy

[kathyayini]

I have structure called
struct senddata
{
int istatus;
char cstrmsg[50];
}sd;

char cSendBuf[100]; //char arr

I wants to copy the data of structure in to cSendBuf. i tried to copy but not successful. code is as follows

memset(&sd, '\0', sizeof(sd));
memset(cSendBuf, '\0', sizeof(cSendBuf));

strcpy(sd.cstrmsg,"Failure###"
sd.istatus = 3;
memcpy(cSendBuf,&sd,sizeof(sd));
printf("msg is :%s\n",cSendBuf);
send(sock_id,cSendBuf,10,MSG_NOSIGNAL); //socketing

what could be the problem.

After memcpy() cSendBuf started with int istatus member content (0x00000003). Your printing as %s terminated on this binary zeroes - that's all...
