Sending structure from client to server

[mvksagar45]

Hi ,
I want to send a structure (user defined) for example :

int empid;
char name[50];
float amount;

} per;

I want to send this from a client to server on unix.Can any1 tell me how to send this(from client) and read the data at the other end(at server).tnx in advance...

Pack your structure on 1 byte boundaries. (#include <pshpack1.h> #include <poppack.h>)

Then just cast a pointer to the structure variable to a const char * when you pass it to the send() function.

On the server end, cast a pointer to the receiving variable to a char * when you pass it to the recv() function.

#include <pshpack1.h>

struct bank{

int empid;
char name[50];
float amount;

};

#include <poppack.h>

void SendBankStruct(SOCKET hSocket,const bank * pBankVar)
{
    send(hSocket,reinterpret_cast<const char *>(pBankVar),sizeof(bank),MSG_WAITALL);
}

void ReceiveBankStruct(SOCKET hSocket,bank * pBankVar)
{
    recv(hSocket,reinterpret_cast<char *>(pBankVar),sizeof(bank),MSG_WAITALL);
}
