The development environment is fedora13 (now it has exceeded 16 ). Vim editor + GCC, G ++ compiler. # Include # include # include # include # include int main (INT argc, char * argv []) {If (argc! = 3) printf ("It's error \ n"); int S, D, C;

In kernel 2.6, initrd. IMG adopts cpio compression. It is no longer in the ext2 format used by kernel 2.4 and cannot be mounted using Mount-o loop. You need to use gunzip to decompress the package, and then use cpio to decompress the package.CP/boot/

Compared with Linux, I found out how stupid windows is. First, if you do not want to use a vfat or NTFS-type low-energy File System in the first partition of your hard disk, Windows will not work (at least Windows 2000 and earlier)Second, install

Compilation and connection: Compile a single source file. -C option, such as gcc-o aa. o-c aa. CPP otherwise, the system will prompt that the main function cannot be found; because some modules only provide Unit functions; there is no main function;

GPL is the product of the hacker spirit, from the birth of C language and Unix PDP-7 to now has more than thirty years of history. They believe that everyone who uses their code is the same as they do, and they have the spirit and ability to

I. Currently, Linux uses the following methods for inter-process communication (IPC: 1. Pipelines (PIPE) and named pipelines (FIFO) 2. Signal) 3. Message Queue 4. Shared Memory 5. semaphores 6. Socket) Ii. IPC details: 1. Pipeline Communication (1)

I. chicken ribs 1. Signal communication: limited amount of information that can be transferred. For pipeline communication, only non-formatted byte streams can be transmitted. This will undoubtedly cause inconvenience to application development. 2.

I. chicken ribs: 1. Thread theory basis (1) Reasons for thread introduction: In Linux, to start a new process, you must allocate it an independent address space and create a large number of data tables to maintain its code segments and stack

I. chicken ribs 1. There are two methods for file programming in Linux: (1) Linux system call (2) c language library functions The difference between the two lies in that (1) it depends on the Linux operating system, and (2) because it is a standard

It took a long time to program the Linux character device for the first time today. The problems found are as follows: Note the following: 1. the compiling module does not need to compile the kernel. Compile the device module in Ubuntu as follows: 2.

Getting started with Linux is a common topic. Many beginners do not know how to learn Linux more effectively. Actually, it's easy to learn about Linux: Read more books and practice more! A good book can help you learn more with less effort. This
