代码如下:

// Global Definitions/Declarations:

typedef void * LOGHANDLE;

typedef LOGHANDLE (STD_CALL *LogOpen_T)
(unsigned char *,
unsigned char *,
unsigned long,
unsigned long *);

LogOpen_T LogOpen;

// Inside some function:
...
LogOpen = (LogOpen_T)ImportSymbol(moduleHandle, "LogOpen" );
if (LogOpen == NULL)
{
err = -2;
}
...

我无法理解这里如何使用 typedef。请解释。
