NAME

6       explain_readdir_or_die - read directory entry and report errors

SYNOPSIS

9       #include <libexplain/readdir.h>
10       struct dirent *explain_readdir_or_die(DIR *dir);
11

DESCRIPTION

13       The explain_readdir_or_die function is used to call the readdir(2) sys‐
14       tem call.  On  failure  an  explanation  will  be  printed  to  stderr,
15       obtained  from  explain_readdir(3),  and then the process terminates by
16       calling exit(EXIT_FAILURE).
17
18       This function is intended to be used in a fashion similar to  the  fol‐
19       lowing example:
20              explain_readdir_or_die(dir);
21
22       dir     The dir, exactly as to be passed to the readdir(2) system call.
23
24       Returns:
25               a  pointer  to  a  dirent  structure, or NULL if end‐of‐file is
26               reached.  On failure, prints an explanation and exits.
