1. Character array Although the string type is more convenient in many aspects of processing strings, it is always at a disadvantage compared to char arrays in terms of calculation speed, and there is no string type in the C language. For subsequent data structure and algorithm courses, as well as hardware development courses, you […]

Use Scrcpy to implement Android phone screen mirroring under Tongxin UOS
Foreword This article mainly records the process of installing Scrcpy under the Tongxin UOS operating system to realize screen mirroring on Android phones. During the installation process, the author referred to many articles, but found that they were not fully introduced. After constant trying and groping, screencasting was finally successfully achieved. Therefore, the original purpose […]

[C language] – String and memory functions (simulate memory function strlen strcpy strcat strcmp…)
This chapter introduces some commonly used functions related to strings or some fixed memory functions, and simulates the implementation of some functions to help you understand more thoroughly. Table of Contents strlen Find the length of the string strcpy string copy strcat append string function strcmp string comparison function Find a string in the strstr […]
Session resource allocation and recycling of unimrcp server
unimrcp uses APR’s memory pool to manage memory. Therefore, a pool pointer is generally passed in the processing function. When memory is needed, a block is allocated from the pool. Generally, there is no need to care about the release of memory. Because, a call is associated with a session, and a session corresponds to […]
