Handshake Functions for Clients
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These functions are used to send and receive handshake packets for a client.
These are only used by low-level clients when the DRIZZLE_CON_RAW_PACKET
option is set, so most applications will never need to use these.
.. c:function:: drizzle_return_t drizzle_handshake_server_read (drizzle_con_st *con)
Read handshake packet from the server in a client.
.. c:function:: drizzle_return_t drizzle_handshake_client_write (drizzle_con_st *con)
Write client handshake packet to a server.
Functions for Servers
^^^^^^^^^^^^^^^^^^^^^
These functions extend the core connection functions with a set of functions
for server application use. These functions allow you to set raw handshake
information for use with the handshake write functions.
.. c:function:: drizzle_return_t drizzle_con_listen (drizzle_con_st *con)
.. c:function:: int drizzle_con_backlog (const drizzle_con_st *con)
.. c:function:: void drizzle_con_set_backlog (drizzle_con_st *con, int backlog)
.. c:function:: void drizzle_con_set_protocol_version (drizzle_con_st *con, uint8_t protocol_version)
.. c:function:: void drizzle_con_set_server_version (drizzle_con_st *con, const char *server_version)
.. c:function:: void drizzle_con_set_thread_id (drizzle_con_st *con, uint32_t thread_id)
.. c:function:: void drizzle_con_set_scramble (drizzle_con_st *con, const uint8_t *scramble)
.. c:function:: void drizzle_con_set_capabilities (drizzle_con_st *con, drizzle_capabilities_t capabilities)
.. c:function:: void drizzle_con_set_charset (drizzle_con_st *con, drizzle_charset_t charset)
.. c:function:: void drizzle_con_set_status (drizzle_con_st *con, drizzle_con_status_t status)
.. c:function:: void drizzle_con_set_max_packet_size (drizzle_con_st *con, uint32_t max_packet_size)
.. c:function:: void drizzle_con_copy_handshake (drizzle_con_st *con, drizzle_con_st *from)
.. c:function:: void * drizzle_con_command_read (drizzle_con_st *con, drizzle_command_t *command, size_t *offset, size_t *size, size_t *total, drizzle_return_t *ret_ptr)
.. c:function:: void * drizzle_con_command_buffer (drizzle_con_st *con, drizzle_command_t *command, size_t *total, drizzle_return_t *ret_ptr)
Handshake Functions for Server
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These functions are used to send and receive handshake packets in a server.
.. c:function:: drizzle_return_t drizzle_handshake_server_write (drizzle_con_st *con)
Write server handshake packet to a client.
.. c:function:: drizzle_return_t drizzle_handshake_client_read (drizzle_con_st *con)
Read handshake packet from the client in a server.
