我试图在C中声明一个回调例程,如下所示：
void register_rename (int (*function) (const char *current,const char *new));
/*------------------------------------------------------------*/
/* WHEN: The callback is called once each time a file is received and
* accepted. (Renames the temporary file to its permanent name)
* WHAT: Renames a file from the given current name to the specified new name.
*/
但是,我收到以下错误：
line 204: error #70:
incomplete type is not allowed
void register_rename (int (*function) (const char *current,const char *new));
我不知道如何纠正这个问题.我在同一个头文件中声明了其他类似的回调例程,我没有收到此错误.
请帮忙！
