alloc_device_t Ссылка на структуру
#include < gralloc.h >
Каждая структура данных устройства должна начинаться с hw_device_t, за которым следуют общедоступные методы и атрибуты, специфичные для модуля.
Определение в строке 326 файла gralloc.h .
| int(* alloc)(struct alloc_device_t *dev, int w, int h, формат int, использование int, buffer_handle_t *handle, int *stride) |
Документация для этой структуры была создана из следующего файла:
