Bit operation is common in kernel, the following is an example of the __set_bit function to analyze its principle:The kernel/include/asm-generic/bitops/non-atomic.h header file has the following /** * __set_bit-set a bit in memory * @nr: The bit to set * @addr: The address to start counting from * * Unlike Set_bit (), this function was non-atomic and may be reordered. * If it ' s called on the same region of memory simultaneously, the

| _ ioc_write (bidirectional ).The kernel defines the _ IO (), _ ior (), Iow (), and _ IOWR () macros to help generate the above cmd. The following describes the implementation of _ IO (). Others are similar: You can see the definition of _ IO () in ASM-generic/IOCTL. h.: # DEFINE _ IO (type, NR) _ IOC (_ ioc_none, (type), (NR), 0) Let's look at the definition of _ IOC ().: # DEFINE _ IOC (Dir, type,

Awk processes data input from multiple files. awk has two sources: standard input and file. The latter method supports multiple files. Www.2cto.com For example: 1. shell Pathname Expansion mode: awk '{...} '*. txt #*. txt is first interpreted by shell and replaced with all * in the current directory *. txt, # If 1.txtand 2.txt are included in the current directory, the command is awk '{...} '1.txt 2.txt 2. specify multiple files directly: awk '{...} 'a.txt B .txt c.txt... # awk's processing proc
