Device and method for detecting memory leak

Abstract

The invention discloses a device and a method for detecting memory leak. The method comprises the following steps: step S202, after a memory is successfully distributed, updating memory distribution times and recording the memory distribution times and memory distribution information into a log file; step S204, when a parameter pointer is not idle and has been distributed, releasing the memory, updating memory releasing times and size, recording the times and the size into the log file, and deleting the memory distribution information from the log file; and step S206, according to the memory distribution times and the size and the memory releasing times and the size in the log file, determining the times and size of the memory not released. The method can count memory using information, detect incorrect memory release and detect memory leak information, and is quite convenient for a programmer to adjust programs so as to enhance the stability of the programs.

Description

Technical field [0001] The present invention relates to the field of computer programming, and more specifically, is a universal device and method for detecting program memory leaks. Background technique [0002] With the development of embedded technology, more and more fields are applied to embedded technology. In the embedded field, due to the limited resources and performance requirements, programming languages ​​in this field generally use the C language. As we all know, a feature of the C language is the dynamic allocation of memory. Dynamic allocation of memory can flexibly use limited memory resources, but the problem it brings is memory leakage. For memory leaks, it is generally difficult to find out except using specific tools. However, memory leaks often cause serious problems such as software crashes. [0003] The limitation of using specific tools is that these software tools are very dependent on the CPU chip. If you change a different chip, you cannot use a dedicat...

For memory leaks, except for using specific tools, it is generally difficult to find

However, memory leaks often cause serious problems such as software crashes.

[0003] The limitation of using specific tools is that these software tools are highly dependent on the CPU chip. If you replace a different chip, you cannot use a dedicated memory testing tool for testing.
