recently on the Hi3515 Debug QT and DVR program, found that they use Message Queuing communication between, leisure, summed up the message queue, hehe, think it easy to understand, at the same time, in the application also found a strong message queue. About thread management (mutex and condition variables) see:Linux Thread Management Prerequisites: Resolving Mutex and conditional variables First, the characteristics of message queues 1. Message Q

If your work has long been associated with a field, such as a long-term development of direct volume rendering (DVR), you may often use your own transfer function class, If you add the. h and. cpp files of the transfer function class to each project, you'll be in trouble, in fact, we can use your own class as you would with the OpenGL library, by encapsulating your written class into a DLL, as follows: The first step: Making DLLsUsing VC6 to create a

In actual work, especially servers, it usually requires 7x24 hours. For this reason many system programs have a server crash after their own restart function, that is, watchdog (watchdog function). For example: Unmanned DVR (Digital video Recorder digital hard disk recorder), the program will automatically reboot (reset) After an exception occurs. However, if the system uses Windows Server platform, how to skip password logon, automatic access to Wind

Porting real-time device drivers to embedded Linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. Linux has occupied the embedded system market like a storm. According to industry analysts, about 1/3 to 1/2 of the New 32-bit and 64-bit embedded systems are designed to use Linux. Embedded Linux has shown its advantages in many application fields, such as SOHO home network and imaging/multi-functional peripherals, and has a huge developm

In general, to simplify the definition of variables of the function pointer type and improve the readability of the program, we need to customize the function pointer type. Typedef void (* PCB) (char *); A callback function can be called by a program like a normal function, but it can be called a callback function only when it is passed as a parameter to the called function. Example of the called function: Void getcallback (PCB callback){/* Do something */}When ca
