Linux新手:Linux vs POSIX手册 [英] Linux newbie: Linux vs POSIX manual

问题描述

$ apropos mkfifo
mkfifo (1)           - make FIFOs (named pipes)
mkfifo (1posix)      - make FIFO special files
mkfifo (3)           - make a FIFO special file (a named pipe)
mkfifo (3posix)      - make a FIFO special file
mkfifoat (3)         - make a FIFO (named pipe) relative to a directory file ...

因此，我有Linux程序员手册和POSIX程序员手册的手册页.我应该更喜欢哪个，为什么?(我正在编写Linux应用程序，没有计划将其移植到AIX，BSD等)

So I have man pages for Linux Programmer’s Manual and POSIX Programmer’s Manual. Which should I prefer and why? (I'm writing a Linux application, no plans to port it AIX, BSD etc)

谢谢.

推荐答案

基本上，Linux手册是来自其编写者的命令/API的文档.POSIX 手册来自 POSIX 标准.通常，正常"的代码更短更小，但是要处理特定的实现；POSIX 的更长更详细(请参阅man 3p read)，但只说明标准中的内容.

Basically, the linux manuals are documentation of the commands/APIs from their writers; The POSIX manuals are from the POSIX standard. Usually, the "normal" ones are shorter and terser, but deal with the specific implementation; the POSIX ones are longer and more detailed (see man 3p read), but only tell what is in the standard.

最好是同时查看两者.
