RTT常用資料類型

標籤：

RTT常用資料類型定義在rtdef.h中

/* RT-Thread basic data type definitions */typedef signed   char                   rt_int8_t;      /**<  8bit integer type */typedef signed   short                  rt_int16_t;     /**< 16bit integer type */typedef signed   long                   rt_int32_t;     /**< 32bit integer type */typedef unsigned char                   rt_uint8_t;     /**<  8bit unsigned integer type */typedef unsigned short                  rt_uint16_t;    /**< 16bit unsigned integer type */typedef unsigned long                   rt_uint32_t;    /**< 32bit unsigned integer type */typedef int                             rt_bool_t;      /**< boolean type *//* 32bit CPU */typedef long                            rt_base_t;      /**< Nbit CPU related date type */typedef unsigned long                   rt_ubase_t;     /**< Nbit unsigned CPU related data type */typedef rt_base_t                       rt_err_t;       /**< Type for error number */typedef rt_uint32_t                     rt_time_t;      /**< Type for time stamp */typedef rt_uint32_t                     rt_tick_t;      /**< Type for tick count */typedef rt_base_t                       rt_flag_t;      /**< Type for flags */typedef rt_ubase_t                      rt_size_t;      /**< Type for size number */typedef rt_ubase_t                      rt_dev_t;       /**< Type for device */typedef rt_base_t                       rt_off_t;       /**< Type for offset *//* boolean type definitions */#define RT_TRUE                         1               /**< boolean true  */#define RT_FALSE                        0               /**< boolean fails */

/* RT-Thread error code definitions */#define RT_EOK                          0               /**< There is no error */#define RT_ERROR                        1               /**< A generic error happens */#define RT_ETIMEOUT                     2               /**< Timed out */#define RT_EFULL                        3               /**< The resource is full */#define RT_EEMPTY                       4               /**< The resource is empty */#define RT_ENOMEM                       5               /**< No memory */#define RT_ENOSYS                       6               /**< No system */#define RT_EBUSY                        7               /**< Busy */#define RT_EIO                          8               /**< IO error */

現在感覺問題：類型帶_t，容易與後續指標混淆，定義的後續實體變數指標都帶_t，如：

typedef struct rt_device *rt_device_t;
