name_to_handle_at, open_by_handle_at - получение описателя для пути и открытие
файла через описатель

ОБЗОР

#define _GNU_SOURCE /* Смотрите feature_test_macros(7) */
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

int name_to_handle_at(int dirfd, const char *pathname,

int open_by_handle_at(int mount_fd, struct file_handle *handle,
int flags);

ОПИСАНИЕ

Функциональное назначение openat(2) было разделено на две части и добавлено в
системные вызовы name_to_handle_at() и open_by_handle_at(): name_to_handle_at()
возвращает описатель с произвольной формой(opaque), который соответствует
указанному файлу; open_by_handle_at() открывает файл по описателю, который был
возвращён предыд ... Читать дальше »
