OS-based electronic products usually burn kernel to norfash, because it can be read and written by byte, but norflash is more expensive than NAND Flash, in addition, NAND Flash is based on block read/write, for example, one-time read/write of 512

When there are frequently used modules in our program and such modules are also used in other programs, we should generate libraries based on the idea of software reuse, so that later programming can reduce the amount of development code. Here we

There are different methods for determining whether a file exists! I usually use two methods: open and access; The two methods have similarities and differences. The following describes their differences in detail: Open is a function used to open,

Select is still important in socket programming, but it is not very popular for beginners of socket programming, they are just used to writing blocking programs such as connect, accept, Recv, or recvfrom (the so-called blocking method block, as the

The shared memory zone is the fastest available in the IPC format. Once such a memory zone is mapped to the address space of the process that shares it, the data transfer between these processes will no longer involve the kernel (here, the meaning
