Dear friends,
               Pls any one could help me how to get out of this problem. my problem is I have declared global structure

as 

 struct vnc_virtual_handshake {
        char vnc_cli_version[20] ;
        char auth_result[5];
        char share_desktop_flag[5];
        char client_encodings[66];
        char client_pixel_frmt[50];
        char client_frame_buf_upreq[20];
        int new_server_cfd1;
        };
 struct vnc_virtual_handshake vnc_seamless_handshake;

and I am receiving some data from server like bellow 

local_receive_len = recv(connSock, buf, PKT_BUFSIZ, 0);

and my big confusion is how to assign or copy the content of above "buf"
char array into structure variable ? but I am doing like bellow 
memcpy(vnc_seamless_handshake.vnc_cli_version, buf , local_receive_len);

similarly for remaining variables in the structure I am receiving from multiple receives and assigning 

is it correct way ?

else pls suggest

and also after filling whole structure I am sending to another function their I am accessing using bellow 

struct vnc_virtual_handshake *vnc_seamless_conn_estmnt = (struct vnc_virtual_handshake *)vnc_seamless_handshake;

and sending to remote as bellow 

send(server_fd, &(vnc_seamless_conn_estmnt->vnc_cli_version), sizeof(vnc_seamless_conn_estmnt->vnc_cli_version), 0);

send(server_fd, &(vnc_seamless_conn_estmnt->auth_result), sizeof(vnc_seamless_conn_estmnt->auth_result), 0);

send(server_fd, &(vnc_seamless_conn_estmnt->share_desktop_flag), sizeof(vnc_seamless_conn_estmnt->share_desktop_flag), 0); 


is I am doing correct way of assigning after recv function and sending correct 
please suggest 

Best Regards 
Babu
