谁知道这个简单函数返回值？？？(15分)

&nbsp; &nbsp; &nbsp;有关串口问题：<br>&nbsp; &nbsp; &nbsp; &nbsp; 请问哪位大哥知道setcommstate这个API函数的返回值？<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;小弟就剩下这么一点“钱”了，全部家当！！！

BOOL SetCommState(<br><br>&nbsp; &nbsp; HANDLE hFile, // handle of communications device<br>&nbsp; &nbsp; LPDCB lpDCB // address of device-control block structure<br>&nbsp; &nbsp; <br>&nbsp;<br><br>Parameters<br><br>hFile<br><br>Identifies the communications device. The CreateFile function returns this handle. <br><br>lpDCB<br><br>Points to a DCB structure containing the configuration information for the specified communications device. <br><br>&nbsp;<br><br>Return Values<br><br>If the function succeeds, the return value is nonzero.<br>If the function fails, the return value is zero. To get extended error information, call GetLastError.

If the function succeeds, the return value is nonzero.<br>If the function fails, the return value is zero.<br>To get extended error information, call GetLastError.

楼上的竟然比我快了1分钟~~~~~~[!]

接受答案了.
