    <p>I have a very big problem... I'm working with sockets in C. I send a request to the server which sends me many responses. The problem is that the client receives the first response and then the connection is closed. What can I do? I tried with <code>setsockopt()</code>... SO_KEEPALIVE or SO_LINGER but I haven't resolved the problem. Can you help me? Thanks a lot </p> <hr> <p>To be more clear here is the code. The socket is automatically closed after a certain amount of time or after the client received the first response... I'm not sure.</p> <pre><code>char* demarre_client( client_args * c_args,char* message, /*char* SERVEUR_PORT*/int port){ int socket_client=socket(PF_INET,SOCK_STREAM,0); memset(&amp;(c_args-&gt;adresse_serveur),0,sizeof(c_args-&gt;adresse_serveur)); c_args-&gt;adresse_serveur.sin_family=AF_INET; c_args-&gt;adresse_serveur.sin_addr.s_addr=inet_addr(SERVEUR_IP); //int port=APHash(SERVEUR_PORT,strlen(SERVEUR_PORT)); c_args-&gt;adresse_serveur.sin_port=htons(port); int err=0; if ((err=connect(socket_client, (struct sockaddr *) &amp;(c_args-&gt;adresse_serveur), sizeof(c_args-&gt;adresse_serveur)))&lt;0) { printf("CONNECT error %d\n", errno); exit(-1); } if (send(socket_client, message, strlen(message), 0)!=strlen(message)) { printf("send error!!\n"); exit(-2); } char* raspFin=(char* )malloc(sizeof(char)*1024); strcpy(raspFin,""); int num=-1; int nn=0; char* rasp=(char* )malloc(sizeof(char)*1024); memset (rasp, 0, 1024 * sizeof(char )); /* here it reads the first response and after he get out of while */ while ((num=recv(socket_client, rasp,1024,MSG_WAITALL))&gt;0) { printf("recu %s mun=%d\n" , rasp,num); strcat(raspFin,rasp); strcat(raspFin,"\n"); rasp=(char* )malloc(sizeof(char)*1024); memset (rasp, 0, 1024 * sizeof(char )); } if (num&lt;0) { printf("rasp error!!\n"); exit(-3); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
