Detailed Description

Functions to communicate with and/or set options on a client. Functions that operate on Ecore connection client objects, these are announced using ECORE_CON_EVENT_CLIENT_ADD by servers created with ecore_con_server_add().

This set of functions, as explained in Ecore Connection Server Functions, is used to send data to a client, or to set options and get information about this client. Most of them should be used on the server, applied on the client object.

If you need to implement a client, the way to connect to a server is described in Ecore Connection Server Functions.

An example of usage of these functions can be found at:
•   Ecore_Con - Creating a client

Function Documentation

  ECORE_CON_API int ecore_con_client_send (Ecore_Con_Client * cl, const void * data, int size)
Sends the given data to the given client.
Parameters
    cl The given client.
    data The given data.
    size Length of the data, in bytes, to send.
Returns
    The number of bytes sent. 0 will be returned if there is an error.
This function will send the given data to the client as soon as the program is back to the main loop. Thus, this function returns immediately (non-blocking). If the data needs to be sent now, call ecore_con_client_flush() after this one.

  ECORE_CON_API void * ecore_con_client_del (Ecore_Con_Client * cl)
Closes the connection and free memory allocated to the given client.
Parameters
    cl The given client.
Returns
    Data associated with the client.
Examples
ecore_con_server_example.c, and ecore_con_server_simple_example.c.

  ECORE_CON_API void ecore_con_client_data_set (Ecore_Con_Client * cl, const void * data)
Sets the data associated with the given client to data.
Parameters
    cl The given client.
    data What to set the data to.
Examples
ecore_con_server_simple_example.c.

  ECORE_CON_API void * ecore_con_client_data_get (Ecore_Con_Client * cl)
Retrieves the data associated with the given client.
Parameters
    cl The given client.
Returns
    The data associated with cl.
Examples
ecore_con_server_simple_example.c.

  ECORE_CON_API const char * ecore_con_client_ip_get (const Ecore_Con_Client * cl)
Gets the IP address of a client that has connected.
Parameters
    cl The given client.
Returns
    A pointer to an internal string that contains the IP address of the connected client in the form 'XXX.YYY.ZZZ.AAA' IP notation.
The returned string should not be modified, freed or trusted to stay valid after deletion for the cl object. If no IP is known NULL is returned.
Examples
ecore_con_server_example.c, and ecore_con_server_simple_example.c.

  ECORE_CON_API void ecore_con_client_flush (Ecore_Con_Client * cl)
Flushes all pending data to the given client.
Parameters
    cl The given client.
This function will block until all data is sent to the server.

  ECORE_CON_API double ecore_con_client_uptime_get (const Ecore_Con_Client * cl)
Checks how long a client has been connected.
Parameters
    cl The client to check
Returns
    The total time, in seconds, that the client has been connected to the server
This function is used to find out how long a client has been connected for.
Examples
ecore_con_server_simple_example.c.
References ecore_time_get().

  ECORE_CON_API double ecore_con_client_timeout_get (const Ecore_Con_Client * cl)
Gets the default time after which the client will be disconnected when inactive.
Parameters
    cl The client object.
Returns
    The timeout, in seconds, to disconnect after.
This function is used to get the idle timeout for a client. A value of < 1 means the idle timeout is disabled.
See also
    ecore_con_client_timeout_set()

  ECORE_CON_API void ecore_con_client_timeout_set (Ecore_Con_Client * cl, double timeout)
Sets the time after which the client will be disconnected when inactive.
Parameters
    cl The client object
    timeout The timeout, in seconds, to disconnect after
This function is used by the server to set the idle timeout on a specific client. If the client becomes idle for a time higher than this value, it will be disconnected. A value of < 1 disables the idle timeout.
This timeout is not affected by the one set by ecore_con_server_timeout_set(). A client will be disconnected whenever the client or the server timeout is reached. That means, the lower timeout value will be used for that client if ecore_con_server_timeout_set() is used on the server.

  ECORE_CON_API Eina_Bool ecore_con_client_connected_get (const Ecore_Con_Client * cl)
Returns whether the client is still connected.
Parameters
    cl The given client.
Returns
    EINA_TRUE if connected, EINA_FALSE otherwise.
Examples
ecore_con_server_simple_example.c.
References EINA_FALSE.

  ECORE_CON_API int ecore_con_client_port_get (const Ecore_Con_Client * cl)
Returns the port that the client has connected to.
Parameters
    cl The client
Returns
    The port that cl has connected to, or -1 on error Use this function to return the port on which a given client has connected.
Examples
ecore_con_server_simple_example.c.

  ECORE_CON_API Ecore_Con_Server * ecore_con_client_server_get (const Ecore_Con_Client * cl)
The server the client is connected to.
Parameters
    cl The client
Returns
    The server the client is connected to.
Examples
ecore_con_server_simple_example.c.

  ECORE_CON_API int ecore_con_client_fd_get (const Ecore_Con_Client * cl)
Gets the fd that the client is connected to.
Parameters
    cl The client object
Returns
    The fd, or -1 on failure
This function returns the fd which is used by the underlying client connection. It should not be tampered with unless you REALLY know what you are doing.
Since
    1.1

  ECORE_CON_API Eina_Bool ecore_con_ssl_client_upgrade (Ecore_Con_Client * cl, Ecore_Con_Type ssl_type)
Upgrades a connection to a specified level of encryption. Use this function to begin an SSL handshake on a connection (STARTTLS or similar). Once the upgrade has been completed, an ECORE_CON_EVENT_CLIENT_UPGRADE event will be emitted. The connection should be treated as disconnected until the next event.
Parameters
    cl The client object.
    ssl_type The SSL connection type (ONLY).
Returns
    EINA_FALSE if the connection cannot be upgraded, otherwise EINA_TRUE.
Warning
    Setting a wrong value for ssl_type WILL mess up your program.
