Deposit and voice data is returned to other application programs use.
Hook (Hook), is Windows（Windows）One platform of message processing facility, application program is permissible
Sub- journey is set above to monitor certain message of specified window, and the window being monitored can be other processes is created
's.After message reaches, before target window process function, process it.Hook Mechanism allows application program intercepting and capturing to process
Windows messaging or particular event.
Detailed implementation is illustrated in fig. 2 shown below：
Introduce an implication that part is illustrated first as follows：
Application program：Want to obtain the program of voice data；Fig. 2 show n application process.
Player process：Sound data sources, are acquired the target program of sound.
Transmission channel ID（Identity, mark）：Can be with program process ID and player process ID as key-value pair
Set up system globally unique 64 ID, the high-order process ID for application program 32, low level is player 32
Process ID, represents which application program wishes to obtain the sound of which player.
Transmission channel allocation table：This exterior and the interior face stores transmission channel ID.
Transmission channel：This is with transmission channel ID for the globally unique shared drive block of the system of mark foundation, is used for
Transmission voice data, player writes data, and application program reads out data.
Transmission channel table：This transmission channel table in player process, for storing transmission channel address.
Voice data caches buf：It is used for caching the voice data from player process intercept.
Distribution monitors thread：This thread monitors transmission channel allocation table, and when allocation table has altered, this thread can scan whole
Individual table, checks each transmission channel ID, checks whether that application program is wanted to obtain the voice data of this player process, if
Have, then update corresponding for this transmission channel ID transmission channel address in transmission channel table.
Transfer voice thread：This thread reads the transmission channel address in transmission channel table, then by voice data one by one
The corresponding transmission channel of write.
Application program obtains the flow process of player voice data, also refers to shown in Fig. 2, specific as follows：
Step 1, application program are initially injected target and play process, then link up with the play function of broadcasting process, and distribution is slow
Deposit（buf）The voice data that storage is intercepted and captured, creates distribution and monitors thread and sound line journey；
For example：Qtalk（A team's voice communication instrument supporting multi-person speech exchange）Program injection player obtains
Sound.
Step 2, application program generate transmission channel ID with oneself ID and player ID for mark, and with this transmission channel ID
Set up transmission channel for mark；
Step 3, application program update transmission channel ID in transmission channel allocation table, and notify player process to carry out
Update；As shown in Figure 2, application process can also change transmission channel ID of itself in channel allocation table.
Step 4, the distribution of player process monitor that thread scans transmission channel allocation table monitors transmission channel allocation table
Distributing altering, finds that application program wants to obtain the sound of oneself, then the address of transmission channel is stored in transmission channel table；As
The situation that fruit has altered occurs, then need to update transmission channel table；
Step 5, the transfer voice thread of player process cache, from voice data, the voice data taking out intercepting and capturing buf,
Then take out transmission channel address from transmission channel table, then write data to corresponding transmission channel；
Hereafter step 6, application program read voice data from each self-corresponding transmission channel.
If other application programs also want to obtain the sound of this player, repeat step（2）Arrive（6）?；If application
Program is not desired to obtain voice data, just deletes transmission channel ID in transmission channel allocation table, and the distribution of player monitors line
Journey detects This move and just deletes corresponding transmission channel address in local transmission channel table, simultaneously closes off corresponding transmission logical
Road.
This technical scheme supports that multiple application programs obtain the voice data of destination player simultaneously, thus enable users to by
The local music play shares multiple voice-enabled chat rooms simultaneously, and the switch of each application program background music is all mutual in addition
Independently being independent of each other so that Qtalk background music function is easy to use and powerful, bring more preferable experience to user.

In embodiments of the present invention, transmission means can be realized in the way of using shared memory block, shared memory block
Can be shared drive, it should be noted that transmission channel can also be other system object, therefore transmission channel information also may be used
To be other, below citing should not be construed as the unique restriction to the embodiment of the present invention.Come real by the way of shared memory block
Existing concrete scheme is as follows：Alternatively, above-mentioned gap marker indicates the destination address that source data is deposited；Above-mentioned processor 680,
Include for above-mentioned source data is sent to above-mentioned target process：For leaving source data in above-mentioned destination address, for target
Process reads.
Based on the aforementioned implementation using shared address block, how the embodiment of the present invention deposits target data if additionally providing
It is put into the specific implementation in the address of gap marker instruction, specific as follows：Above-mentioned processor 680, for depositing source data
It is placed on above-mentioned destination address, read for target process and include：For reading the ground of above-mentioned gap marker instruction using transmission thread
Location, and source data is write the address of above-mentioned gap marker instruction, read for target process.
In embodiments of the present invention, transmission channel information can be stored in by target process, and concrete scheme is as follows：Above-mentioned process
Device 680, the transmission channel information for obtaining each target process includes：For being injected using hook by target process in originating process
Afterwards, obtain the transmission channel information being stored in by the target process injecting above-mentioned originating process using hook.
It should be noted that in above-mentioned data transfer device embodiment, included unit is simply patrolled according to function
Volume divided, but be not limited to above-mentioned division, as long as being capable of corresponding function；In addition, each function list
