gSoap not sending more than 4 bytes of response

Question

I have the following code for sending the response, but only the first 4 bytes are sent in response. Why the behaviours is like this?

int sendRaw(struct soap *soap, const char *respMsg)
{          
        if (soap_response(&objSoap, SOAP_FILE)) /* OK HTTP response header */
        { 
                soap_end_send(&objSoap);
                return soap->error;
        }
        for(int i = 0; i < sizeof(respMsg); i++)
        {
                if(soap_send_raw(&objSoap,&respMsg[i],1))
                {
                        return soap_end_send(&objSoap);
                }    
        }
        soap_end_send(&objSoap);
        return SOAP_OK;
}

and my calling is like this

  const char  msg = "this is a rest response";      
  return sendRaw(&objSoap,msg); 

Answer 1

Since respMsg is a char *, it's size equates that of any other pointer in your system, which given your problem description appears to be 4 bytes (32 bits):

    for(int i = 0; i < sizeof(respMsg); i++)

If respMsg is a string, then use strlen(respMsg) [this is the case in your little example], if it is some kind of binary data, then you will need to pass along the actual size.
