usual, and sendto () will still return. If you do not know before, this will surprise you. This also shows that UDP does not confirm data packets.
TCP transmits stream data, that is to say, there is no segmentation in the middle, which leads to a common problem of sticking packets, so we need to package and unpackage, common methods are Byte Length + data, such as websocket. That is to say, we accept the data once, which may be the data set sent by the other Party multiple times, or some data s

After the machine is started, it will automatically enter the familiar Linux installation screen, and then follow the on-screen prompts to operate. During the installation process, the installation program requires us to select the installation method and the location of the image file. The options are Local CDROM, Hard drive, NFS images, FTP, and HTTP

Any I/O requests generated by the customer's operating system will be intercepted midway through and re-sent to the user mode simulated by the QEMU process.KVM provides memory virtualization through/dev/kvm devices. Each customer's operating system has its own address space, which is mapped when the customer's operating system is instantiated. The physical memory mapped to the customer's operating system is actually the virtua

ObjectiveThe function of the digital-to-analog converter DAC is much smaller than the timer Tim, the serial port Usart, and so on, which is why the internal integrated DAC module is not so many. However, in a project that requires the use of a digital-to-analog conversion function, this DAC module can basically replace the plug-in DAC chip, because this module is also very powerful, only need to be simple configuration can output the specified voltage signal (such as: PWM waveform, triangular wa
)->funcptr)? 2. funcptr (i.e. __main_block_func_0 ) is not a parameter type __main_block_impl_0 *, why Clang compiled out is __block_impl*. In fact, no matter what the type is, it passed test as a parameter, there is no error. Okay, so here's a summary of Midway simplicity: ignoring the complex branch of the middle, leaving the main line, when we declare a block variable A and assign it a value, we actually create a function pointer Ptra, and then gen
