The C language as a standard programming language on Linux systems gives us great control over dynamic memory allocation. This freedom can lead to serious memory management problems that can cause a program to crash or cause performance degradation over time.A memory leak (that is malloc() , an internal call that is free() never freed after execution) and a buffer overflow (for example, writes to memory previously allocated to an array) are common problems that may be difficult to detect. This s

This article mainly explains the use of remote debugging tools, and using a PB simulator to test. First, simulator The simulator (emulator) is a part of the PB. Dedicated to debugging the kernels and applications created under the PB. The simulator can simulate the physical platform of Windows CE under the PC. But in fact it's just a user program running at the

What is the ADB? The ADB's full name is Android Debug Bridge, which is the role of the debugging bridges. Through the ADB we can debug the Android program through DDMS in Eclipse, which is the Debug tool. The ADB works in a special way, allowing the IDE and QEMU to communicate by listening to ports such as socket TCP 5554, which by default will daemon the associated network port, so the ADB process runs automatically when we run eclipse.

Valgrind is a GPL software used for memory debugging and code analysis of Linux (for x86, amd64 and ppc32) programs. You can run your program in its environment to monitor memory usage, such as malloc and free in C or new and delete in C ++. With the valgrind toolkit, You can automatically detect many memory management and thread bugs, avoiding spending too much time searching for bugs, making your program more stable.Valgrind's main functions The val

located in the upper corner and select Profile in the new pop-up window.Xcode will start Instruments . Instruments displays a drop-down window and lists all available components. Select Allocations . Instruments will then launch the app and open the Instruments main window.The Allocations component displays a table that exits all memory allocations that the app has performed. Because the data is much more, filtering first lists only the objects created by our own code. First draw several lines
