So this is my function (server)
Code:
int main(int argc, char **argv) {
    
    // Set Up
    int socket_fd, new_socket_fd, num; // file descriptors, and port number
    socklen_t client_length; // size of client address 
    struct sockaddr_in serv_addr, cli_addr;
    char buffer[MAXDATASIZE]; // input gets put here

    // Set Up Socket
    for(num=0;num<CONSIGNMENT;num++) client_names[num]=NULL;   // set all to Null 
    bzero(buffer,MAXDATASIZE); // Set all to zero
    socket_fd = socket(AF_INET, SOCK_STREAM, 0); // create a listening socket to the internet
    if (socket_fd < 0) error("ERROR opening socket"); // check the socket
    bzero((char *) &serv_addr, sizeof(serv_addr)); // sets all values in the serv_addr to 0
    serv_addr.sin_family = AF_INET; // set up the information for the server
    serv_addr.sin_addr.s_addr = INADDR_ANY;
    serv_addr.sin_port = htons(PORT);
    if (bind(socket_fd, (struct sockaddr *) &serv_addr, sizeof(serv_addr)) < 0) error("ERROR on binding"); // check the bind
    listen(socket_fd,5); // sets it up for listening, max of 5 waiting connections while one is being handled             
    client_length = sizeof(cli_addr);
    
    while(1) {
        new_socket_fd = accept(socket_fd, (struct sockaddr *) &cli_addr, &client_length); // pause process until client connects
        if (new_socket_fd < 0) error("ERROR on accept"); // check new file descriptor

     // server and client talks....


        close(new_socket_fd); 
    }
    
    close(socket_fd); // close connections with client
    return(0); 
}

is the while loop supposed to be like this, the server should be able to connect with any number of clients, and any of the clients should be about to talk to the server at any time...

NAME
tcrmttest - test cases of the remote database API DESCRIPTION
The command `tcrmttest' is a utility for facility test under multi-thread situation. This command is used in the following format. `host' specifies the host name of the server. `rnum' specifies the number of iterations. tcrmttest write [-port num] [-tnum num] [-nr] [-rnd] [-ext name] host rnum Store records with keys of 8 bytes. They change as `00000001', `00000002'... tcrmttest read [-port num] [-tnum num] [-mul num] host Retrieve all records of the database above. tcrmttest remove [-port num] [-tnum num] host Remove all records of the database above. Options feature the following. -port num : specify the port number. -tnum num : specify the number of running threads. -nr : use the function `tcrdbputnr' instead of `tcrdbput'. -rnd : select keys at random. -ext name : call a script language extension function. -mul num : specify the number of records for the mget command. If the port number is not more than 0, UNIX domain socket is used and the path of the socket file is specified by the host parameter. This command returns 0 on success, another on failure. SEE ALSO
