NAME
explain_readdir_or_die - read directory entry and report errorsSYNOPSIS
#include <libexplain/readdir.h>struct dirent *explain_readdir_or_die(DIR *dir);
DESCRIPTION
The explain_readdir_or_die function is used to call the readdir(2) system call. On failure an explanation will be printed to stderr, obtained from explain_readdir(3), and then the process terminates by calling exit(EXIT_FAILURE).This function is intended to be used in a fashion similar to the following example:
explain_readdir_or_die(dir);
- dir
- The dir, exactly as to be passed to the readdir(2) system call.
- Returns:
- a pointer to a dirent structure, or NULL if end‐of‐file is reached. On failure, prints an explanation and exits.
SEE ALSO
- readdir(2)
