C++ (Cpp) make_ext4fs_sparse_fd Beispiele

Beispiel #1

Datei: engine.c Projekt: c-ong/platform_system_core

void generate_ext4_image(struct image_data *image)

     * But unfortunately it is not portable as it is not clear whether this
     * function opens file in TEXT or BINARY mode.
     *
     * There are also some reports it is buggy:
