explain_telldir_or_die - current location in directory and report errors
#include <libexplain/telldir.h> off_t explain_telldir_or_die(DIR *dir); off_t explain_telldir_on_error(DIR *dir);
The explain_telldir_or_die function is used to call the telldir(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_telldir(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_telldir_on_error function is used to call the telldir(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_telldir(3) function, but still returns to the caller. dir The dir, exactly as to be passed to the telldir(3) system call.
The explain_telldir_or_die function only returns on success, see telldir(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_telldir_on_error function always returns the value return by the wrapped telldir(3) system call.
The explain_telldir_or_die function is intended to be used in a fashion similar to the following example: off_t result = explain_telldir_or_die(dir);
telldir(3) return current location in directory stream explain_telldir(3) explain telldir(3) errors exit(2) terminate the calling process
