Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The embodiment of the invention discloses asynchronous processing method and system between a kind of process based on IPC, to realize between process
High efficiency collaborative work.
See Fig. 1, asynchronous processing method between a kind of based on IPC process that the embodiment of the present invention provides, including:
S101, receive the first message structure body；Described first message structure body includes message header and message content, described in disappear
Breath head includes message type information, message echo message and responds mark；If described message echo message is responded for needs, then will
The response corresponding with described first message structure body processes function and is stored in internal queues；
Wherein, after the response process function corresponding with described first message structure body is stored in internal queues, also include:
The overtime timer corresponding with described first message structure body is stored in timer queue；
Concrete, the concrete message structure in the present embodiment includes:
Message header messageheader in the present embodiment comprise type of message type, the need of response needAck,
Whether it is in response to message isAck.Whole message m essage includes message header messageheader and body.
Concrete, seeing Fig. 2, the transmission timing figure provided for the present embodiment, after receiving the first message structure body, it is judged that
Whether the message echo message in the first message structure body is responded for needs, if desired responds, then will be with described message structure body
Corresponding response processes function and is stored in internal queues, and starts overtime timer and be pressed into timer queue；By the first message knot
Structure body is sent to receiving terminal, i.e. first thread in this programme, after first thread receives and processed message, fills in the second message
Structure, the second message structure body is response message, and response message is sent second to receiving thread, i.e. this programme
Thread, receiving thread timeing closing device and call correspondence response process function process.
S102, first thread receive described first message structure body, and the process function calling correspondence processes, and generates
Second message structure body；The response of described second message structure body is designated receives the response；
Wherein, described first thread receives described first message structure body, and the process function calling correspondence processes, bag
Include:
Described first thread receives described first message structure body, believes according to the type of message of described first message structure body
Breath, the process function corresponding from the first array of function pointer inquiry processes.
S103, the second thread receive described second message structure body, obtain corresponding response from described internal queues and process
Function processes.
Wherein, if the response mark in the message structure body of described second thread reception is not receiveed the response, then according to institute
Stating the message type information of message structure body, the process function corresponding from the second array of function pointer inquiry processes.
After the most described second thread receives described second message structure body, also include:
Obtain corresponding overtime timer from described timer queue, if described overtime timer has not timed out, then close institute
State overtime timer；If described overtime timer is overtime, then the time-out function calling correspondence processes.
Concrete, see Fig. 3, the receiving terminal handling process schematic diagram provided for the present embodiment, the second thread receives the
After two message structure bodies, it is judged that the response of the second message structure body identifies whether for receiveing the response, the most then to judge the second message
Structure is response message, then take out a corresponding intervalometer from timer queue and close, and processes function team from response
Row take out corresponding response and processes function process message.If non-response message, then directly invoke phase according to type of message
The message processing function answered processes.
Concrete, the present embodiment provides asynchronous processing method between a concrete process:
First, called by msgget system in the middle of two communication process and open two identical message queue QueueA
And QueueB, define a series of type of message with shaping, and define the first array of function pointer arraryFuncA, these letters
The function that number pointer points to is for processing the message of the type that QueueA sends, and type of message is array index, definition
Second array of function pointer arraryFuncB, the function that these function pointers point to is used for processing that QueueB sends
The message of type, type of message is array index.Receiving terminal startup first thread ThreadA of QueueA is used for circulating reception and disappears
Breath, the receiving terminal of QueueB starts the second thread ThreadB for circulating reception message.
Further, by interfaceA when QueueA sends information, need to fill in message structure body, if this message is
Need response, then need the response receiveed the response process function is put into internal queues listFunc, start time-out simultaneously
Intervalometer (intervalometer is once considered as time-out to the time, can perform timeout treatment function), and overtime timer is put into timing
Device queue listTime.
When processing message, if first thread ThreadA receives message, look into according to type of message from arraryFuncA
Ask alignment processing function to process.After process completes, if needing the message responded, then fill in the second message structure body,
Comprising type of message, type is to receive the response, and fills out and specifically respond content in message body, by interfaceB, this message is sent out
Deliver in the second thread QueueB.
When second thread ThreadB receives message, if receiveing the response, then from listTime, take out overtime timer
And close, from listFunc, take out process function of receiveing the response process.If not receiveing the response, then according to message class
Type takes out message processing function from arraryFuncB and processes.
Based on technique scheme, this programme also includes:
Reception processes function expansion instruction；
Add corresponding process function according to the instruction of described process function expansion, and update the first array of function pointer and the
Two array of function pointers.
Concrete, in the present embodiment, if desired it is extended, it is only necessary to add type of message and corresponding Message Processing
Function, if needing asynchronous process to receive the response, also needs increase to receive the response process function.
Concrete, this programme does not has cyclic query logic, during without business, there is no CPU usage；Meeting when message completes
Receive return response, and preset response can be called process function and process；Easily extension, only need to increase type of message and disappear
Breath processes function just can increase New function；Response processes function and sends function setup condition flag, it is possible to by asynchronous process
Changing synchronizing process into process, it is achieved mode is simple, efficiency is high, manages and safeguards that easily flow chart of data processing can be tracked,
Extensibility is high, thus realizes the high efficiency collaborative work between process.
