如图,可以看到两个文件同时打开一个文件,两个同时写文件,可能会造成写覆盖的情况,必须使用原子操作函数才可以。 头文件 fcntl.h 也就是file control,提供了对文件描述符的各种操作 int open(const char* path, int oflag, ...); int openat(int fd, const char* path, int oflag, ...); path是要打开或...
在Unix-like系统中,设置目录以使所有创建的文件和子目录继承其权限通常涉及使用SetUID,SetGID和Sticky Bit以及Access Control Lists (ACLs)的概念。以下是如何设置目录以实现权限继承的指南: 设置SetGID位:SetGID(设置组ID)位使新创建的子目录继承其父目录的组,新创建的文件也将具有与父目录相同的组。使用chmod命令设...
