The main functions of the operating system are resource management, program control and human-computer interaction. The resources of a computer system can be divided into two categories: equipment resources and information resources. Device resources refer to the hardware devices that make up the computer, such as the central processing unit, main memory, disk storage, printers, tape storage, monitors, keyboard input devices, and mice. Information resources refer to various data stored in the computer, such as files, program libraries, knowledge bases, system software and application software, etc.
What is the program that opens the file and C related procedures independently of the operating system?
What is the operating system independent way to open files with related programs from C? Is there a solution in Boost, or something similar?
More specifically, it can cover Windows, Mac OS X
How to write a C function that is binding to open a file handle in RUST?
I have played with writing library bindings in Rust, and it’s not difficult. However, now, I’m stuck: I’m trying to write a binding for librsync, and it’s Some functions expect you to pass an open
From the single-chip microcomputer to the operating system 7 – In-depth understanding of the delay mechanism of Freertos
If you haven’t studied the source code of the operating system, it’s not considered learning the operating system.
Time management includes two aspects: system beat and task delay management.
How to choose a server operating system
A server is needed to build a website. In the process of purchasing a server, in addition to the common CPU, memory, hard disk, bandwidth and other configurations, users also need to choose the ope
Operating system core principle -3. Process principle (medium): process schedule
PS: In a multi-process concurrent environment, although conceptually, there are multiple processes executing at the same time, but under a single CPU, at any time Only one process can be in the exe
CRC test vector of crc16 (ccitt)
Does anyone know some CRC test vectors of CRC16-CCITT?
I don’t have a trusted CRC implementation. I either need to test someone’s implementation or test my own implementation. (For CRC32, I u
The operating system is upgraded from Tizen 2.3.2.3 to Tizen 3.0.0.1, the signature error in Gear S3 is incorrect.
My Gear S3 is running on Tizen 2.3.2.3. Yesterday, I updated it to Tizen 3.0.0.1. Now, when I try to install the app from Tizen Studio 1.2, it The following error is displayed

Arrays – Decrease performance when you store handle objects in unit arrays
I only have a small part of MATLAB code that has a lot of performance issues, I hope you can learn how to improve it:
I am developing an agent-based Simulation, it creates many handle objects
Add Const-Ness to the Opaque handle
If I create a C module, it provides the user with a pointer to the forward declaration structure, as shown below:
typedef struct FOO_Obj *FOO_Handle; If I then declare the function prototype
