Refer to the help documentation, First, check whether there are few header files. The second is that the library used has not been added. For example, the library libsock. So needs to be added to the socket. Add a method. If you use IDE, go to project> Properties> qnx c/C ++ project> linker.Category = extra LibrariesAdd sock. Not before or after. (Use QNX target to select the library file //// c: \ qnx

the time of the Interrupt Service program execution and reduce the scheduling wait time, the best way to implement the ISR in the operating system is to set the flag to construct a short ISR when the interrupt occurs, and the other work to create the corresponding thread to execute separately. It's like someone calls you, and when you suddenly get a mission instruction, you spend a lot of time on the phone while you're on the telephone, or you hang up and do a specific task. Of course the latte

Before and we introduced the method of thread synchronization on QNX Metux and Semophore, two methods can be used to lock one or several resources to avoid conflict of resource usage. In another case, a thread needs to use the thread synchronization method, barrier, to continue execution after another thread has finished working.To give a realistic example, suppose there are three soldiers operating an antiaircraft gun, one responsible for filling she

I. Priority and task Preemption Neutrino provides a priority-driven preemptible design concept. Priority-driven means that we can assign a priority to each thread, which can obtain CPU resources based on the priority scheduling policy. If a

Like most of my friends, I used to only use the SD card SPI mode. This mode is simple and can be implemented on most single-chip computers without the need for CRC verification. The SD mode can achieve simultaneous transmission of four data lines,

How to delete a value from an array in Perl This article mainly introduces how to delete a value from an array in Perl? This article explains how to assign an array element to undef and then delete the element from the array. For more information, see I'm not sure whether undef has a definite relationship with the value removed from the array. I guess if we think of undef as "null", there will be some connections. But in general, assigning something to undef is different from deleting something.
