Recent project uses rabbit, the client uses rabbitmq-c library, the number of Chinese online no explanation, so the use of the function summarized:
amqp_new_connection
Function operates: allocates and initializes a new connection object amqp
The function prototype: amqp_connection_state_t amqp_new_connection (void);
Parameters: None
Return value: the successful return amqp connection object, failed to return NULL
amqp_tcp_socket_new
Function role: to create tcp socket
函数原型：amqp_socket_t * amqp_tcp_socket_new(amqp_connection_state_t state);
Parameters: amqp connection object
Return value: the successful return tcpsocket, failed to return NULL
amqp_socket_open_noblock
Function operates: nonblocking open socket connection
函数原型：int amqp_socket_open_noblock(amqp_socket_t *self, const char *host,int port, struct timeval *timeout);
Parameters: self socket socket
host ip
port port
timeout connection timeout
Returns: 0 on success, non-zero failure
amqp_login
Function role: Login rabbitmq
函数原型：amqp_rpc_reply_t amqp_login(amqp_connection_state_t state, char const *vhost, int channel_max, int frame_max, int heartbeat, amqp_sasl_method_enum sasl_method, ...);
Parameters: state amqp connection object
vhost virtual host
channel_max channel maximum number of connections, 0 for no limit
frame_max client communication and maximum allowed frame size. The default value is 131072, increase this help increase throughput, reduce delay helps reduce the value
heartbeat heartbeat interval, the heartbeat 0 off, only support part of the functions of the heart
sasl_method authentication MQP_SASL_METHOD_PLAIN: with two parameters const char * username, and const char * password.AMQP_SASL_METHOD_EXTERNAL: const with the parameter char * identity.
Returns: the results
amqp_channel_open
Function operates: channel open connection
函数原型：amqp_channel_open_ok_t *amqp_channel_open(amqp_connection_state_t state, amqp_channel_t channel);
Parameters: state amqp connection object
channel connecting channel
Return value: channel_id
amqp_exchange_declare
Function role: Declare exchange
函数原型：amqp_exchange_declare_ok_t *amqp_exchange_declare(amqp_connection_state_t state, amqp_channel_t channel,amqp_bytes_t exchange, amqp_bytes_t type, amqp_boolean_t passive,amqp_boolean_t durable, amqp_boolean_t auto_delete, amqp_boolean_t internal,amqp_table_t arguments);
Parameters: state amqp connection object
channel connecting channel
exchange switch
type switch type fanout direct broadcast direct binding theme topic fuzzy match
If 1 passive, but did not exist before the switch, it will return a failure
durable 1 0 persistent non-persistent
After the exchange is not binding auto_delete 1 0 queue does not remove deleted
internal 0 1 can be used directly can not be used directly, use only bind to other exchange
arguments extended parameters
Return value: channel_id
amqp_queue_declare
Function role: statement queue
函数原型：amqp_queue_declare_ok_t *AMQP_CALLamqp_queue_declare(amqp_connection_state_t state, amqp_channel_t channel, amqp_bytes_t queue,amqp_boolean_t passive, amqp_boolean_t durable, amqp_boolean_t exclusive,amqp_boolean_t auto_delete, amqp_table_t arguments);
Parameters: state amqp connection object
channel connecting channel
queue queue
If 1 passive, but did not exist before the queue, it will return a failure
durable 1 0 persistent non-persistent
When the connection is not exclusive 1 the current time, the current queue 0 connection is not automatically delete the queue is not automatically deleted
1 when no auto_delete consumer, the queue 0 is automatically deleted without consumer, the queue is not automatically deleted
Return value: channel_id
amqp_queue_bind
Function operates: Binding switch queues and
函数原型：amqp_queue_bind_ok_t *AMQP_CALL amqp_queue_bind(amqp_connection_s tate_t state, amqp_channel_t channel, amqp_bytes_t queue,amqp_bytes_t exch ange, amqp_bytes_t routing_key, amqp_table_t arguments);
Parameters: state amqp connection object
channel connecting channel
queue queue
exchange switch
routing_key route
arguments extended parameters
Return value: channel_id
amqp_basic_publish
Function role: dissemination of information
函数原型：int amqp_basic_publish(amqp_connection_state_t state, amqp_channel_t channel,amqp_bytes_t exchange, amqp_bytes_t routing_key, amqp_boolean_t mandatory,amqp_boolean_t immediate,structamqp_basic_properties_t_ const *properties, amqp_bytes_t body);
Parameters: state amqp connection object
channel connecting channel
exchange switch
routing_key route
mandatory 1 message must be routed to the queue that is otherwise fail
immediate 1 If the message does not subscribe, return failure
properties properties
message body member
Return Value: success
amqp_basic_consume
Function role: the beginning of a queue consumer
函数原型：amqp_basic_consume_ok_t * amqp_basic_consume(amqp_connection_statet state, amqp_channel_t channel, amqp_bytes_t queue, amqp_bytes_t consumer_tag, amqp_boolean_t no_local, amqp_boolean_t no_ack, amqp_boolean_t exclusive, amqp_table_t arguments);
Parameters: state amqp connection object
channel connecting channel
queue queue
consumer_tag consumer identity
no_local 1 does not receive the reception 0
no_ack 1 no reply 0 recovery
When the connection is not exclusive 1 the current time, the current queue 0 connection is not automatically delete the queue is not automatically deleted
arguments extended parameters
Returns: result
amqp_consume_message
Function role: receiving a message
函数原型：amqp_rpc_reply_t amqp_consume_message(amqp_connection_state_t state, amqp_envelope_t *envelope, struct timeval *timeout, int flags);
Parameters: state amqp connection object
