+ * This case checks the basic functionality of the execveat(2):
+ * 1) When pathname is relative, it is relative to the directory where
+ * the executed process is located and the dirfd is the descriptor of
+ * the directory.
+ * 2) When pathname is relative and dirfd is the special value AT_FDCWD,
+ * the pathname is the relative to the current working directory of
+ * the calling process.
+ * 3) When pathname is absolute, dirfd can be ignored.
+ * 4) When pathname is an empty string and the flag AT_EMPTY_PATH is
+ * specified, dirfd specifies the file to be executed.
