It stores the files to the server, get it and It stores the files to the server, get it and execute from the server.execute from the server.

PROBLEM DEFINITION

The existing vi editor has modes The existing vi editor has modes named insert mode and command named insert mode and command mode used to type a program, to save, mode used to type a program, to save, to delete etc., really working in this to delete etc., really working in this editor becomes tedious, and it will give editor becomes tedious, and it will give headaches to the clients. headaches to the clients.

The program which we have developed The program which we have developed in C helps us to communicate with the in C helps us to communicate with the editor.editor.

SOCKET

Socket( ) is the end-end connection Socket( ) is the end-end connection between the systems.between the systems.

SyntaxSyntax::int socket(int domain, int type, int socket(int domain, int type, int protocol);int protocol);1. Domain is set as "1. Domain is set as "AF_INETAF_INET“. “. 2. Type argument specifies the kernel 2. Type argument specifies the kernel of the of the socket “socket “SOCK_STREAM”.SOCK_STREAM”.3. Protocol to "3. Protocol to "00". ".

BIND

Bind( ) method associates the socket with a port Bind( ) method associates the socket with a port on the client machine.on the client machine.

Syntax:Syntax:int bind(int sockfd, struct sockaddr int bind(int sockfd, struct sockaddr *my_addr, int addrlen);*my_addr, int addrlen);1. 1. sockfdsockfd is the socket file descriptor is the socket file descriptor returned by socket( ).returned by socket( ).2. 2. my_addrmy_addr is a pointer to a struct is a pointer to a struct sockaddr that contains information about sockaddr that contains information about your address, namely, port and IP address.your address, namely, port and IP address.3. 3. addrlenaddrlen can be set to sizeof(struct can be set to sizeof(struct sockaddr).sockaddr).

CONNECT

Connect( ) is used to connect the remote host from Connect( ) is used to connect the remote host from the server.the server.

Syntax:Syntax:int connect(int sockfd, struct sockaddr int connect(int sockfd, struct sockaddr *serv_addr, int addrlen);*serv_addr, int addrlen);1. sockfd is the socket file descriptor,returned 1. sockfd is the socket file descriptor,returned by the socket( ) call.by the socket( ) call.2. serv_addr is a struct sockaddr containing 2. serv_addr is a struct sockaddr containing the destination port and IP address.the destination port and IP address.3. addrlen can be set to sizeof(struct 3. addrlen can be set to sizeof(struct sockaddr).  sockaddr).  

LISTENListen( ) waits for incoming connections Listen( ) waits for incoming connections

int listen(int sockfd, int backlog);int listen(int sockfd, int backlog);1. backlog is the number of 1. backlog is the number of connections allowed on the incoming connections allowed on the incoming queue i.e. the incoming connections queue i.e. the incoming connections are going to wait in this queue until are going to wait in this queue until the accept( ) fires. the accept( ) fires.

SEND & RECIEVESEND & RECIEVE

These two functions are for These two functions are for communicating over stream sockets or communicating over stream sockets or connected datagram sockets.connected datagram sockets.

sockfdsockfd is the socket descriptor is the socket descriptor where data is to be sent.where data is to be sent.

msgmsg is a pointer to the data you is a pointer to the data you want to send.want to send.

lenlen is the length of that data in is the length of that data in bytes.bytes.
