meaning that when you execute the program, it runs as though the file owner is the user instead of you. Many programs use this setuid bit to run as root in order to get the privileges they need to change system
For example, if you add -s to the kernel parameters, the kernel passes the -s to the init program to indicate that it should start in single-user mode. 当遇到无法理解的参数时,Linux内核会保存该参数。内核在执行用户空间启动时会将该参数传递给init。例如,如果您添加了-s到内核参数中,内核会将-...
Enums in C are used to define a set of named integral constants that represent a set of related values. Here are some situations where enums are commonly used: Improving Code Readability: Enums make code more readable by providing descriptive names for integral constants. For example, instead...
Once the installation is complete, it’s a good practice to confirm that CMake has been installed correctly by checking its version. This step also provides the installed version number, which can help verify compatibility with specific projects or build systems. Run the following command to check...

The third variable ‘TARGET’ contains the name of the program for which we need to build the executable. The measure advantage of this variation of the makefile is that we just need to change the values of the variables that we have used whenever there is some change in the compiler, co...
Statement expressions that make it possible to specify declarations and statements in expressions Block-scope label names The article also demonstrates how to use the new C compiler features for creating generic macros on example of linked-list manipulation-routines. Such macros semantically mimic C++ ...
