Linux的全称是“Linux is not Unix”(Linux不是Unix的缩写)。这个名称反映了Linux内核的起源和设计目标,即虽然它受到了Unix操作系统的启发,但它并不是Unix的一个直接衍生物,而是一个独立开发的操作系统内核。因此,选项A是正确的。 这个题目涉及到Linux的全称,需要考虑Linux的起源和名称的含义。首先,需要了解Linux的...
Linux and Unix are two terminologies that are interchangeably used to refer to the same Operating system. This is largely due to their striking similarities and few are not able to draw a distinction between the two. In the Linux vs Unix conundrum, there exists confusion on which system does...

Unix “一切皆文件” 退化成了“一切皆文件描述符”: *** 一切皆文件**: 文件属于Unix/Linux目录树,编址于统一命名空间。 *** 一切皆文件描述符:** 文件描述符属于进程打开文件表,进程内可见。 AI检测代码解析 同样奇怪的是pipe调用,它创建了一对文件描述符,但也仅仅是文件描述符,而没有被纳入到统一命名空...

Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()). Extensive documentation can be found on the project wiki: ...
