Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated it will be appreciated that described herein
Preferred embodiment is merely to illustrate and explains the present invention, is not intended to limit the present invention.
In correlation technique, in the running of subprocess, needing the environmental variable using parent process, and
Need to change the occurrence of the environmental variable of parent process, when just can normally complete operation, it usually needs stop fortune
Row subprocess, and exit subprocess, reenter parent process, the environmental variable of modification parent process, Ran Houchong
New operation parent process, just can complete the change of environmental variable；After environmental variable is successfully changed, again again
Enter subprocess, make subprocess again start anew to run, the amended environment that could inherit parent process becomes
Amount, then normally completes operation.This, during running subprocess, needing to change parent process
During environmental variable, need first to exit subprocess, rerun the environmental variable that parent process just can complete parent process
Modification scheme, operating process is comparatively laborious, and has had a strong impact on operational efficiency and the speed of subprocess.
In order to solve above-mentioned technical problem, the embodiment of the present disclosure provides a kind of processing method of thread parameter,
The program of the adjustment be applied to voice data recognition result for the method, system or device, as shown in figure 1,
Step s101, creates far call thread corresponding with sub-line journey；
Step s102, when sub-line journey is run, judges whether to need to change the first parameter information in parent process；
Step s103, when judged result is to need to change the first parameter information, calls far call thread；
Step s104, runs far call thread, to change the first parameter information.
When running subprocess, the first parameter information if necessary to modification parent process is it is possible to call and son
Thread corresponding far call thread, then runs this far call thread it is possible to realize not exiting son
Process, do not reenter parent process to change the first parameter information of parent process on the basis of, automatically by
Far call thread is modified to the first parameter information in parent process, to simplify the first parameter of parent process
The modification operation of information, allows subprocess to run without interruption simultaneously, ensures that the fortune of subprocess
Line efficiency and speed.
As shown in Fig. 2 in one embodiment, step s101 can be performed as:
Step a1, processes function by the remote thread in locally created far call thread and creates remotely

By applying for processing the internal memory of function for storing the first parameter information and remote thread in parent process,
And after successfully applying for internal memory, the first parameter information and remote thread can be processed function write parent process,
Far call thread can be write parent process, such far call thread is just shared in identical with parent process
Deposit, so that subprocess can change the first parameter information in parent process by far call thread.
In one embodiment, when judged result is to need to change the first parameter information, call far call
Thread, comprising:
When judged result is to need to change the first parameter information, will be with the first parameter information pair by subprocess
The second parameter information answered is transferred to remote thread and processes function to call far call thread；
Run far call thread, to change the first parameter information, comprising:
When remote thread processes function and receives the second parameter information, transported according to the second parameter information
OK, to change the first parameter information.
When needing to change the first parameter information in parent process, will can be believed with the first parameter by subprocess
Cease corresponding second parameter information to be transferred to remote thread process function to call this far call thread, and by
Share identical internal memory in far call thread with parent process, therefore, process function in remote thread and receive
This second parameter information and by second parameter information run after it is possible to directly repair to the first parameter information
Changing, thus realizing not exiting subprocess, not reentering parent process to change the first parameter letter of parent process
On the basis of breath, automatically by far call thread, the first parameter information in parent process can be repaiied
Change, to simplify the modification operation of the first parameter information of parent process, allow subprocess without interruption simultaneously
Run, ensure that operational efficiency and the speed of subprocess.
