I used the second method, which is very convenient: # define gettid () syscall (_ nr_gettid) Where gettid () is used after linux2.4, linux uses nptl as its own thread library. to be compatible with the POSIX standard, there are two domain tgid and TID in the kernel task. The former is the process ID and the latter is the thread

In Linux, each file has its own users and groups of users, by default the creator of the file, or by Chown and chgrp, to modify the users and user groups to which the file belongs. The properties of the file are stored in the attribute structure stat, which is marked by St_uid and St_gid. Let me give you an example. Suppose that there are now two users in the system, Liz and HLF, who have a program file whose user is HLF. Then use the Liz User login

In Embedded Linux, hard disk formatting is often involved. fdisk is a commonly used tool, which is powerful and implements fdisk in busybox. When the fdisk implemented by busybox is a simplified version, it is quite different from the GNU fdisk in the original version, mainly because it lacks some detailed functions.This article mainly describes an optional
