for a code snippet. What is the purpose of this?In protected mode, the code snippet is not writable, so-called non-writable does not mean that the physical nature of the memory changed, so that the memory is not written, but that the code snippet descriptor access to the corresponding memory area, the processor does not allow to write data or change data.However, if you want to modify the code snippet, is there a way? Yes, that is to create a new descriptor for the code snippet, such as a reada

Linux Platform x86 compilation (16): Invoking C library functions in assembly language

, we write our own library is static link, and the system's library generally use dynamic link. Dynamic linking does not link the function code to the executable program, and the dynamic link library is called by the operating system when the program starts. On Linux systems, the standard C dynamic library is located in the libc.so.x file, where x values represent the version of the library. In order to link the libc.so file, you must use the-l parameter of the GNU connector, which is linked in
