Detailed Description
Function that reconstruct and prepare packet of Eet Data Serialization to be send.
Function Documentation
EAPI Eet_Connection* eet_connection_new | ( | Eet_Read_Cb * | eet_read_cb, |
Eet_Write_Cb * | eet_write_cb, | ||
const void * | user_data | ||
) |
Instanciate a new connection to track.
- Parameters
-
eet_read_cb Function to call when one Eet_Data packet has been fully assemble. eet_write_cb Function to call when one Eet_Data packet is ready to be send over the wire. user_data Pointer provided to both functions to be used as a context handler.
- Returns
- NULL on failure, or a valid Eet_Connection handler.
For every connection to track you will need a separate Eet_Connection provider.
- Since
- 1.2.4
EAPI int eet_connection_received | ( | Eet_Connection * | conn, |
const void * | data, | ||
size_t | size | ||
) |
Process a raw packet received over the link.
- Parameters
-
conn Connection handler to track. data Raw data packet. size The size of that packet.
- Returns
- 0 on complete success, any other value indicate where in the stream it got wrong (It could be before that packet).
Every time you receive a packet related to your connection, you should pass it to that function so that it could process and assemble packet has you receive it. It will automatically call Eet_Read_Cb when one is fully received.
- Since
- 1.2.4
EAPI Eina_Bool eet_connection_empty | ( | Eet_Connection * | conn | ) |
Tell if the Eet_Connection as received some partial data.
- Parameters
-
conn Connection handler to request.
- Returns
- EINA_TRUE if there is some data pending inside, EINA_FALSE otherwise.
Eet_Connection buffer data until the received data can be unserialized correctly. This function let you know if there is some data inside that buffer waiting for more data to be received before being processed.
- Since
- 1.7
EAPI Eina_Bool eet_connection_send | ( | Eet_Connection * | conn, |
Eet_Data_Descriptor * | edd, | ||
const void * | data_in, | ||
const char * | cipher_key | ||
) |
Convert a complex structure and prepare it to be send.
- Parameters
-
conn Connection handler to track. edd The data descriptor to use when encoding. data_in The pointer to the struct to encode into data. cipher_key The key to use as cipher.
- Returns
- EINA_TRUE if the data where correctly send, EINA_FALSE if they don't.
This function serialize data_in with edd, assemble the packet and call Eet_Write_Cb when ready. The data passed Eet_Write_Cb are temporary allocated and will vanish just after the return of the callback.
- Since
- 1.2.4

EAPI Eina_Bool eet_connection_node_send | ( | Eet_Connection * | conn, |
Eet_Node * | node, | ||
const char * | cipher_key | ||
) |
Convert a Eet_Node tree and prepare it to be send.
- Parameters
-
conn Connection handler to track. node The data tree to use when encoding. cipher_key The key to use as cipher.
- Returns
- EINA_TRUE if the data where correctly send, EINA_FALSE if they don't.
This function serialize node, assemble the packet and call Eet_Write_Cb when ready. The data passed Eet_Write_Cb are temporary allocated and will vanish just after the return of the callback.

EAPI void* eet_connection_close | ( | Eet_Connection * | conn, |
Eina_Bool * | on_going | ||
) |
Close a connection and lost its track.
- Parameters
-
conn Connection handler to close. on_going Signal if a partial packet wasn't completed.
- Returns
- the user_data passed to both callback.
- Since
- 1.2.4
