Description
Technical field
The present invention relates to communication technique field more particularly to a kind of storage method and devices.
Background technology
It is frequently necessary to check the LOG information or protect LOG information that serial ports Program performs in embedded development debugging
It leaves come for analyzing and determining the operation conditions of program.Output redirection would generally be used by preserving in LOG information to some file
" ＞ " is operated.
But the inventors discovered that when debugging some problems, unexpected power down crash is restarted sometimes, at this moment if be used only
LOG information is saved in file by output redirection, and there are no real for the data cached in possible file system buffer at this time
Write-in disk is just as power down suddenly causes to lose.
Invention content
The embodiment of the present invention provides a kind of storage method, and disk is really written not yet for solving data in the prior art
Just as the problem of power down suddenly causes to lose.
A kind of storage method, the method includes：
Capture LOG information；
It is performed simultaneously sync orders；
The data write-in hard disk in caching is preserved after the sync orders are received.
A kind of storage device, described device include：
Handling module, for capturing LOG information；
Execution module, for being performed simultaneously sync orders；
Writing module, for preserving the data write-in hard disk in caching after the sync orders are received.
As it can be seen that method provided in an embodiment of the present invention, can be used for solving data really write-in not yet in the prior art
Disk is just as the problem of power down suddenly causes to lose.
Description of the drawings
It, below will be to embodiment or the prior art in order to illustrate more clearly of the present invention or technical solution of the prior art
Attached drawing is briefly described needed in description.
Fig. 1 is a kind of storage method flow chart provided in an embodiment of the present invention；
Fig. 2 is a kind of structure chart of storage device provided in an embodiment of the present invention.
Specific embodiment
In order to which those skilled in the art is made to more fully understand the technical solution in the embodiment of the present invention, and make the present invention's
Above-mentioned purpose, feature and advantage can be more obvious understandable, technical solution in the present invention made below in conjunction with the accompanying drawings further detailed
Thin explanation.
Method provided in an embodiment of the present invention can be used for solving data in the prior art and disk really be written just not yet
Because the problem of unexpected power down causes to lose.As shown in Figure 1, detailed process is as follows：
Step 11, LOG information is captured；
LOG information is preserved by being captured in the output redirection to file by program in this step, operation is for example：App ＞
log.txt；Wherein, LOG information refers to some sentences printed when program performs；
Step 12, sync orders are performed while step 11 is performed；
In this step, sync orders refer to for by the order of the data cached write-in hard disk in file system buffer；
Step 13, the data write-in hard disk in caching is preserved after the sync orders are received.
As it can be seen that if unexpected power-off is also because the sync orders that cycle performs are thus by the caching in file system buffer
Data are written with hard disk.
As shown in Fig. 2, the embodiment of the present invention provides a kind of storage device, which includes：
Handling module 21, for capturing LOG information；
Execution module 22, for being performed simultaneously sync orders；
Writing module 23, for preserving the data write-in hard disk in caching after the sync orders are received.
In conclusion advantageous effect：
Method provided in an embodiment of the present invention can be used for solving data in the prior art and disk really be written just not yet
Because the problem of unexpected power down causes to lose.
In conclusion advantageous effect：
Method provided in an embodiment of the present invention can be used for solving data in the prior art and disk really be written just not yet
Because the problem of unexpected power down causes to lose.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
