Can the function "connect()" & "listen() + accept()" be used with the same TCP port at the same time ?

[Louie Chan]

Dear sir/madam,

Does anyone know if I can use the functions "listen() & accept()" after one successful TCP connection with the function "connect" ?
Please refer to the following concept codes !!

int sockfd, new_connect_fd;

sockfd = socket(domain, type, protocol);
connect(sockfd, sockaddr, addrlen);			<--- connect() and connection successful !
listen(sockfd, backlog);
new_connect_fd =  accept(sockfd, sockaddr, addrlen);	<--- Can the accept() be used after using connect() ?

Thanks for your help !

Best Regards. Louie
