sockets.h

openmap java写的开源数字地图程序. 用applet实现,可以像google map 那样放大缩小地图.

/*
 * sockets.c - general-purpose routines for opening and using sockets
 *              as server or client.
 *
 * Functions are:
 *
 *      open_socket()                   Open a socket connection
 *      open_socket_port()                      Open a socket connection
 *      close_socket()                  Close a socket connection
 *      accept_socket()                 Accept a connection on a socket
 *
 * Usage:
 *      Servers call open_socket() as servers and then call accept_socket()
 *      to get connections from clients.
 *
 *      Clients call open_socket() and use that socket id to talk to servers.
 *
 *      Both servers and clients call close_socket() to terminate.
