how to read POSIX?

Jim's reply may not make it clear that the letter o is short rather than long.
When Posix first came out, I attended a session where some Posix bigshots introduced themselves and discussed the standard. One person asked how to pronounce P-O-S-I-X. The bigshots had actually discussed this during one of their meetings. In addition to deciding the official pronunciation, they "invented" a little motto to help folks remember. It's "I'm positive about Posix" and the "pos" in both words is pronounced identically. After the meeting they even handed out "I'm positive about Posix" buttons. So get it right if you talk to one of them.... they apparently care.

readdir
READDIR(3) Linux Programmer's Manual READDIR(3) NAME
readdir - read a directory SYNOPSIS
#include <sys/types.h> #include <dirent.h> struct dirent *readdir(DIR *dir); DESCRIPTION
The readdir() function returns a pointer to a dirent structure representing the next directory entry in the directory stream pointed to by dir. It returns NULL on reaching the end-of-file or if an error occurred. According to POSIX, the dirent structure contains a field char d_name[] of unspecified size, with at most NAME_MAX characters preceding the terminating null character. Use of other fields will harm the portability of your programs. POSIX-2001 also documents the field ino_t d_ino as an XSI extension. The data returned by readdir() may be overwritten by subsequent calls to readdir() for the same directory stream. RETURN VALUE
The readdir() function returns a pointer to a dirent structure, or NULL if an error occurs or end-of-file is reached. ERRORS
EBADF Invalid directory stream descriptor dir. CONFORMING TO
