mutual transcoding support: Std::codecvt_utf8 Encapsulates UTF8-related encoding conversions Std::codecvt_utf16 Encapsulates UCS2-related encoding conversions Std::codecvt_utf8_utf16 Encapsulates the encoding conversion of UTF8 and UCS2 for C + + cross-platform development, we often encounter the default with that encoding, we will find that the Windows UCS2 solution is heterogen

Linux kernel source code learning: Zombie processes, Linux kernel source code botnets Orphan and botnets After a normal sub-process fork parent process, the two establish a parent-child relationship. When the child process ends, it notifies the parent process, clears the memory occupied by the child process, and leave

in the Development tree. Once the development tree has been sufficiently developed, the development tree will become a new stable tree. The development number is reflected in the source program version number. The source program version number is in the form of X. y. z: for a stable tree, Y is an even number; for a development tree, Y is one (therefore, an odd number) larger than the corresponding stable tree ). So far, the highest version of the stability tree is 2.4.18; the latest version of

example, if the system does not support SCSI, the SCSI directory does not exist.In addition to the above, there are a number of directories named, they are the process directory. Each process currently running in the system has a corresponding directory under/proc, with the PID number of the process as the directory name, which is the interface to read the process information. The self directory is the information interface of the read process itself

1. Create a kernel for the embedded platform (the 6410 Development Board is used as an example here) 1. Clear the original configuration and intermediate files (1) x86: Make distclean (2) arm: Make distclean 2. Configure the kernel (1) x86: Make menuconfig (2) arm: Make menuconfig arch = arm (platform to be specified) 3. Compile the kernel (1) x86: Make bzimage (

The Linux kernel of Android is stored in the kernel subdirectory. By comparing it with the standard Linux 2.6.25 kernel, we can find that it mainly adds the following content: 1. Add the gold-fish platform based on the ARM architecture. The directories added are as follows:

The MMU manages the tables in the system in the page size unit.32-bit system: Page size 4KB64-bit system: Page size 8KBThe kernel represents each physical page in the system with the corresponding

improvements made in the Development tree can also be applied to the stability tree, the same improvements will be made in the stability tree after tests in the Development tree. Once the development tree has been sufficiently developed, the development tree will become a new stable tree. The development number is reflected in the source program version number. The source program version number is in the form of X. y. z: for a stable tree, Y is an even number. For a development tree, Y is bigge

kernel code that is independent of the architecture. This code is common to all of the processor architectures supported by Linux. Under these codes is an architecture-dependent code that forms part of what is often called a BSP (Board Support Package). The code is used as the processor for a given architecture and platform-specific code. Properties of the

To say clear Systemd, you have to start with the Linux operating system started speaking. The startup of the Linux operating system starts with the BIOS, then the boot Loader loads into the kernel and initializes the kernel. The final step in kernel initialization is to star
