The "OD" command is often used to show the content of a special file: Command name: OD Signature method: od [-abcdfhilovx] [-A ] [-j ] [-n ] [-S ] [- T ] [-W ] [-- help] [-- version] [file...] Description: displays the file content in the

In Linux, dynamic libraries are divided into two parts: 1) Compiling and 2) running. If a dynamic library is used during compilation, you need to add-lpath-LXXX to specify the dynamic library. This is the same as the static library. Here, path is

1, The relationship between the child process and the parent process: When a child process is created, it is almost the same as the parent process. It has the same address space as the parent process and executes the sameCode(Code Execution starts

Generally, the Linux SAMBA service is installed and directly enters the/etc/samba directory. Open smb. conf, [Gloabal] contains some global options that affect all sharing. The main option to be modified is Security =. the default option is

Likely () andUnlikely ()Likely () and unlikely () can be seen everywhere in the 2.6 kernel. Why should they be used? What are the differences between them?First, make it clear: If (likely (value) is equivalent to If (value) If (unlikely (value) is

During Linux kernel module programming, parameters are often required to be passed to the module. The role of parameters is from the device number used to the operations that the driver should perform. for example, a SCSI Adapter Driver often has

1. Because Linux does not use any acceleration tool on CERNET, it is really slow to access the Internet, so I want to share folders with windows in Linux to use some of the previously better stuff! To do this, you need to take the following steps: 1.

The functions or symbols defined in the export_symbol label are public to all kernel code. You can directly call them in your kernel module without modifying the kernel code.Export_symbol can be used to export a function as a symbol to other modules.

Premise: there is not much talk about it, and there is no way to connect with the operator. It is also a talk about too much. How do I import zookeeper? 1. added the-G option to zookeeper. 2. parse the row gdb a. Out (Note: A. out must exist, or

Thread Data Processing Compared with a process, one of the biggest advantages of a thread is data sharing. Each process shares the data segment that follows the parent process to conveniently obtain and modify data. But this also brings many

In Linux, The container_of (PTR, type, member) macro is used to pass in the Member Address PTR domain of the struct type. The first address of the struct variable is returned, which is defined as follows: # Define container_of (PTR, type, member )({\
