Question

調用宏我試圖調用某些宏在我的C程序。沒有參數的宏是可以的，但我得到錯誤如果我添加一個參數。

例如這是我從我的C程序頭文件調用。

/**Retrieve the value from the persistent store for the given key **/ 
#define wifi_cmd_flash_ps_load(KEY) \ 
{\ 
bglib_temp_msg.cmd_flash_ps_load.key=KEY;\ 
bglib_temp_msg.header=(((uint32)wifi_dev_type_wifi|(((uint32)2+0)>>8)))|((((uint32)2+0)&0xff)<<8)|((uint32)0x7<<16)|((uint32)0x4<<24);\ 
bglib_output (4+2,(uint8*)&bglib_temp_msg,0,(uint8*)NULL);\ 
} 


/**Uploading is finished.**/ 
#define wifi_cmd_dfu_flash_upload_finish() \ 
{\ 
bglib_temp_msg.header=(((uint32)wifi_dev_type_wifi|(((uint32)0+0)>>8)))|((((uint32)0+0)&0xff)<<8)|((uint32)0x0<<16)|((uint32)0x3<<24);\ 
bglib_output (4+0,(uint8*)&bglib_temp_msg,0,(uint8*)NULL);\ 
} 

這是一個錯誤，我得到：

什麼建議嗎？

謝謝你的幫助。

Answer 1

在此行中：

bglib_temp_msg.cmd_flash_ps_load.key=KEY;\ 

你似乎沒有定義bglib_temp_msg的結構。目前尚不清楚這是否意味着在函數體做調用它（即主叫方是否意味着有名字的局部變量），還是如我懷疑，你想要的東西，如：

struct mystructuretype bglib_temp_msg; 

第一（很明顯，正確的結構名）。請記住#include或先於相關結構聲明的使用。
