void explain_dup_or_die(int fildes);
DESCRIPTIONThe explain_dup_or_die function is used to call the dup(2) system call. On failure an explanation will be printed to stderr, obtained from explain_dup(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:
- The fildes, exactly as to be passed to the dup(2) system call.
- This function only returns on success. On failure, prints an explanation and exits.
