What functions connect( ) and accept ( ) call in Socket interfacing?

connect() system call:

Clients use procedures connect to initiate connection with an exact server. The form is connect ( socket , saddress, saaddresslen)

Argument socket is the descriptor of a socket upon the client's computer to utilize for the connection. Argument sockaddress is a sockaddr structure which specifies protocol port number and the server's address. Argument saaddresslen identifies the length of the server's address measured in octets.

The client doesn't have to bind a local address before call ing connect( ).

connect( ) inside can call bind() to connect to a local address if not completed previous.

accept() system call:

After a connection oriented server executes the listen( ) system call , a real connect ion from some client process is waited for throgh having the server execute the accept () system call. Therefore the form is:

accept (sockfd, sockaddr * peer, int* addrlen)

Such system call returns up to three values: an integer return code which is either an error indication or a newly socket descriptor, the address of the client process (i.e. peer) and the size of such address(i.e. addrlen).

Accept automatically creates a new socket descriptor, supposing the server is a concurrent server.

While a connection request is obtained, the process forks, along with the child process servicing the connection and also the parent process waits for the other connection request.
