Step 404, recovery memory block flow process.
Shared-memory management method the second embodiment of the present invention; by increase the method that reclaims memory block flow process after deleting internal memory; effectively prevented that the operation of deletion memory block from occurring abnormal; cause the memory block of not deleted completely to remain in internal memory doubly linked list; cause the defect of internal memory waste, thereby realized shared-memory management; a kind of effective shared drive protection mechanism is provided, make application program effectively managing shared memory between.
In shared-memory management method the second embodiment of the present invention, reclaim memory block flow process, as shown in Figure 5, the process flow diagram for the recovery memory block flow process of shared-memory management method the second embodiment of the present invention, specifically comprises as follows:
Step 501, according to recovery command, memory block is reclaimed in application;
Step 502, according to recovery command, pointer moves to the position of described memory block;
Whether step 503, the judgement status indication corresponding with described memory block be for deleting, if deleted execution step 504, if not deleted execution step 505;
Whether step 504, the judgement data area corresponding with described memory block have data message, if there is data message execution step 508, if there is no data message execution step 506;
505 if not delete, and judges whether the data area corresponding with described memory block has data message, if there is data message execution step 507, if there is no data message execution step 508;
Step 506, alarm level is set, and exports described alarm level, execution step 508;
Described memory block is deleted in step 507, the release data field corresponding with described memory block in internal memory doubly linked list, execution step 508;
Step 508, end application.
Like this; by pointer being moved to correspondence memory position; and the state that checks this internal memory whether with record consistent method; having overcome that prior art creates after internal memory chained list cannot the state of effective monitoring data field and the whether consistent defect of the status indication of node area; thereby realized shared-memory management; a kind of effective shared drive protection mechanism is provided, has made application program managing shared memory space effectively, and then stopped to occur in follow-up management RAM leakage or crossed the problem such as delete.
Wherein, after step 507, can also comprise: warning information is set, and exports described warning information.
Shared-memory management method the 3rd embodiment of the present invention

Shared-memory management method the 7th embodiment of the present invention
As shown in figure 11, be the process flow diagram of shared-memory management method the 7th embodiment of the present invention, shared-memory management method specifically comprises as follows:
Step 1101, host process is finished, execution step 1102, corresponding at least one the subprocess of described host process, the internal memory doubly linked list corresponding with described subprocess is positioned at a stack, in described internal memory doubly linked list, include the nodal information corresponding with each memory block, data message and [Dan label information, described nodal information is positioned at node area, described data message is positioned at data field, described [Dan label information is positioned at mark zone, described nodal information at least includes the size of described data field, for representing whether data field has the status indication of data message, the address of forward direction memory block and the address of backward memory block.
Step 1102, check that whether described stack is empty, performs step 1103 if not empty.
Step 1103, judge whether described stack is last stack, if last stack execution step 1107, if not last stack execution step 1104.When realizing, first according to host process, generate an empty stack, then according to each subprocess generating, using the first memory block physical address of the internal memory doubly linked list corresponding with each subprocess as data message, leave in the data field of correspondence memory piece of the internal memory doubly linked list of being managed by described host process.Like this, in the internal memory doubly linked list of host process management, by reading the nodal information of the memory block corresponding with the subprocess of needs judgement, and the backward block address memory that judges memory block described in the internal memory doubly linked list of host process management is " nil ", think that a described stack is last stack, otherwise be not last stack.
Step 1104, check whether internal memory doubly linked list in described stack exists the data field not discharging, the data field execution step 1105 not discharging if exist, the data field execution step 1106 not discharging if do not exist.
Memory block is reclaimed in step 1105, execution, execution step 1102.
Step 1106, described internal memory doubly linked list is released in described stack, finished the subprocess corresponding with doubly linked list in described stack, perform step 1102.
Step 1107, check whether internal memory doubly linked list in described stack exists the data field not discharging, the data field not discharging if exist carries out 1108, the data field execution step 1109 not discharging if do not exist.
Memory block is reclaimed in step 1108, execution, execution step 1109.
Step 1109, described internal memory doubly linked list is released in described stack, finished the subprocess corresponding with doubly linked list in described stack, perform step 1110.
Step 1110, the described host process that finishes.
