Problems solved by technology

[0003] However, no matter whether the application is placed in the ROM space or the RAM space, the size is limited. When there are multiple applications, the dynamic loading middleware platform may not be able to store the space occupied by multiple applications when multiple applications are loaded.

Embodiment 1

[0038] see figure 1 , the embodiment of the present invention provides a method for implementing a dynamic link library, the method comprising:

[0039] Step 101: load the dynamic link library file;

[0040] Step 102: Obtain the address of the service interface provided by the dynamic link library file to other external applications;

[0041] Step 103: release the dynamic link library file.

[0042] In this embodiment, the dynamic link library file itself cannot run independently, and the dynamic link library file is mainly responsible for providing some specific services to other external applications, specifically providing some functions. The dynamic link library file header is fixed to be a query interface with a unified format, which receives the function name and returns the function pointer corresponding to the function name.

[0043] Other external applications refer to software applications. The software platform in the embodiment of the present invention is descri...

Embodiment 2

[0070] see Figure 5 , the embodiment of the present invention provides a device for implementing a dynamic link library, the device includes: a loading module 501, an acquisition module 502 and a release module 503;

[0071] Wherein, the loading module 501 is used to load the dynamic link library file;

[0072] An acquisition module 502, configured to acquire the address of the service interface provided by the dynamic link library file to other external applications;

[0073] The releasing module 503 is configured to release the dynamic link library file loaded by the loading module 501 .

[0074] In this embodiment, the dynamic link library file itself cannot run independently, and the dynamic link library file is mainly responsible for providing some specific services to other external applications, specifically providing some functions. The dynamic link library file header is fixed to be a query interface with a unified format, which receives the function name and retur...

Abstract

The embodiment of the invention discloses a method and a device for realizing a dynamic-link library and belongs to the field of communication. The method comprises: loading a dynamic-link library file; acquiring an interface address of service provided by the dynamic-link library file for other outside applications; and releasing the dynamic-link library file. The device comprises a load module,an acquisition module and a release module. The embodiment of the invention has the advantages that: by loading the dynamic-link library file and unloading the dynamic-link library file after being used, the loading of the dynamic-link library files of a plurality of other outside applications at the same time can be realized; and the dynamic-link library file enables other outside application packages to occupy smaller space, update more convenient and save flowing rate, and also enables the other outside applications to develop more rapidly and conveniently at the same time.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for realizing a dynamic link library. Background technique [0002] Due to its low price and high completion rate, MTK platform is currently the most popular terminal solution and is widely used in various terminal brands. However, because its software platform does not support dynamic loading and online updating of applications, terminal application deployment on the MTK platform can only be burned into the ROM (Read-Only Memory) chip of the terminal during production. The cruel terminal competition makes manufacturers continue to reduce production costs, and the ROM chip space is getting smaller and smaller, which restricts the performance and content of terminal applications and becomes the largest bottleneck in terminal application development. In the prior art, by dynamically loading the middleware platform, when the application is running, the application fi...
