40 * @defgroup Ecore_Con_Group Ecore_Con - Connection functions
42 * The Ecore Connection Library ( @c Ecore_Con ) provides simple mechanisms
43 * for communications between programs using reliable sockets. It saves
44 * the programmer from having to worry about file descriptors and waiting
45 * for incoming connections.
47 * There are two main objects in the @c Ecore_Con library: the @c
48 * Ecore_Con_Server and the @c Ecore_Con_Client.
50 * The @c Ecore_Con_Server represents a server that can be connected to.
51 * It is used regardless of whether the program is acting as a server or
54 * To create a listening server call @c ecore_con_server_add(), optionally using
55 * an ECORE_CON_USE_* encryption type OR'ed with the type for encryption.
57 * To connect to a server, call @c ecore_con_server_connect(). Data can
58 * then be sent to the server using the @c ecore_con_server_send().
60 * Functions are described in the following groupings:
61 * @li @ref Ecore_Con_Lib_Group
62 * @li @ref Ecore_Con_Server_Group
63 * @li @ref Ecore_Con_Client_Group
64 * @li @ref Ecore_Con_Url_Group
66 * Events are described in @ref Ecore_Con_Events_Group.
71 * @defgroup Ecore_Con_Events_Group Ecore Connection Events Functions
73 * @li ECORE_CON_CLIENT_ADD: Whenever a client connection is made to an
74 * @c Ecore_Con_Server, an event of this type is emitted, allowing the
75 * retrieval of the client's ip with @ref ecore_con_client_ip_get and
76 * associating data with the client using ecore_con_client_data_set.
77 * @li ECORE_CON_EVENT_CLIENT_DEL: Whenever a client connection to an
78 * @c Ecore_Con_Server, an event of this type is emitted. The contents of
79 * the data with this event are variable, but if the client object in the data
80 * is non-null, it must be freed with @ref ecore_con_client_del.
81 * @li ECORE_CON_EVENT_SERVER_ADD: Whenever a server object is created
82 * with @ref ecore_con_server_connect, an event of this type is emitted,
83 * allowing for data to be serialized and sent to the server using
84 * @ref ecore_con_server_send. At this point, the http handshake has
86 * @li ECORE_CON_EVENT_SERVER_DEL: Whenever a server object is destroyed,
87 * usually by the server connection being refused or dropped, an event of this
88 * type is emitted. The contents of the data with this event are variable,
89 * but if the server object in the data is non-null, it must be freed
90 * with @ref ecore_con_server_del.
91 * @li ECORE_CON_EVENT_CLIENT_DATA: Whenever a client connects to your server
92 * object and sends data, an event of this type is emitted. The data will contain both
93 * the size and contents of the message sent by the client. It should be noted that
94 * data within this object is transient, so it must be duplicated in order to be
95 * retained. This event will continue to occur until the client has stopped sending its
96 * message, so a good option for storing this data is an Eina_Strbuf. Once the message has
97 * been received in full, the client object must be freed with ecore_con_client_free.
98 * @li ECORE_CON_EVENT_SERVER_DATA: Whenever your server object connects to its destination
99 * and receives data, an event of this type is emitted. The data will contain both
100 * the size and contents of the message sent by the server. It should be noted that
101 * data within this object is transient, so it must be duplicated in order to be
102 * retained. This event will continue to occur until the server has stopped sending its
103 * message, so a good option for storing this data is an Eina_Strbuf. Once the message has
104 * been received in full, the server object must be freed with ecore_con_server_free.
109 * @defgroup Ecore_Con_Buffer Ecore Connection Buffering
111 * As Ecore_Con works on an event driven design, as data arrives, events will
112 * be produced containing the data that arrived. It is up to the user of
113 * Ecore_Con to either parse as they go, append to a file to later parse the
114 * whole file in one go, or append to memory to parse or handle leter.
116 * To help with this Eina has some handy API's. The Eina_Binbuf and
117 * Eina_Strbuf APIs, abstract dynamic buffer management and make it trivial
118 * to handle buffers at runtime, without having to manage them. Eina_Binbuf
119 * makes it possible to create, expand, reset and slice a blob of memory -
120 * all via API. No system calls, no pointer manipulations and no size
123 * Additional functions include adding content at specified byte positions in
124 * the buffer, escaping the inputs, find and replace strings. This provides
125 * extreme flexibility to play around, with a dynamic blob of memory.
127 * It is good to free it (using eina_binbuf_free()) after using it.
129 * Eina_Binbuf compliments Ecore_Con use cases, where dynamic sizes of data
130 * arrive from the network (think http download in chunks). Using
131 * Eina_Binbuf provides enough flexibility to handle data as it arrives and
132 * to defer its processing until desired, without having to think about
133 * where to store the temporary data and how to manage its size.
135 * An example of how to use these with Ecore_Con follows.
140 * #include <Ecore_Con.h>
143 * data_callback(void *data, int type, void *event)
145 * Ecore_Con_Event_Url_Data *url_data = event;
146 * if ( url_data->size > 0)
148 * // append data as it arrives - don't worry where or how it gets stored.
149 * // Also don't worry about size, expanding, reallocing etc.
150 * // just keep appending - size is automatically handled.
152 * eina_binbuf_append_length(data, url_data->data, url_data->size);
154 * fprintf(stderr, "Appended %d \n", url_data->size);
162 * completion_callback(void *data, int type, void *event)
164 * Ecore_Con_Event_Url_Complete *url_complete = event;
165 * printf("download completed with status code: %d\n", url_complete->status);
167 * // get the data back from Eina_Binbuf
168 * char *ptr = eina_binbuf_string_get(data);
169 * size_t size = eina_binbuf_length_get(data);
171 * // process data as required (write to file)
172 * fprintf(stderr, "Size of data = %d bytes\n", size);
173 * int fd = open("./elm.png", O_CREAT);
174 * write(fd, ptr, size);
177 * // free it when done.
178 * eina_binbuf_free(data);
180 * ecore_main_loop_quit();
187 * main(int argc, char **argv)
190 * const char *url = "http://www.enlightenment.org/p/index/d/logo.png";

741 * @defgroup Ecore_Con_Server_Group Ecore Connection Server Functions
743 * This group of functions is applied to an @ref Ecore_Con_Server object. It
744 * doesn't mean that they should be used in the server application, but on the
745 * server object. In fact, most of them should be used in the client
746 * application, when retrieving information or sending data.
748 * Setting up a server is very simple: you just need to start it with
749 * ecore_con_server_add() and setup some callbacks to the events
750 * @ref ECORE_CON_EVENT_CLIENT_ADD, @ref ECORE_CON_EVENT_CLIENT_DEL and
751 * @ref ECORE_CON_EVENT_CLIENT_DATA, that will be called when a client is
752 * communicating with the server:
755 * if (!(svr = ecore_con_server_add(ECORE_CON_REMOTE_TCP, "127.0.0.1", 8080, NULL)))
758 * ecore_event_handler_add(ECORE_CON_EVENT_CLIENT_ADD, _add_cb, NULL);
759 * ecore_event_handler_add(ECORE_CON_EVENT_CLIENT_DEL, _del_cb, NULL);
760 * ecore_event_handler_add(ECORE_CON_EVENT_CLIENT_DATA, _data_cb, NULL);
762 * ecore_main_loop_begin();
765 * The function ecore_con_server_connect() can be used to write a client that
766 * connects to a server. The resulting code will be very similar to the server
770 * if (!(svr = ecore_con_server_connect(ECORE_CON_REMOTE_TCP, "127.0.0.1", 8080, NULL)))
773 * ecore_event_handler_add(ECORE_CON_EVENT_SERVER_ADD, _add_cb, NULL);

775 * ecore_event_handler_add(ECORE_CON_EVENT_SERVER_DATA, _data_cb, NULL);
777 * ecore_main_loop_begin();
780 * After these two pieces of code are executed, respectively, in the server and
781 * client code, the server will be up and running and the client will try to
782 * connect to it. The connection, with its subsequent messages being sent from
783 * server to client and client to server, can be represented in the following
