WIN32 Error Handling

The following is excerpted from:
Http://baike.baidu.com/view/8552073.htm?fr=aladdin

For example:

1 voidTesterrorinfo (void)2 {3 //make an error. 4 if(! CreateDirectory (_t ("c:\\"),0))5 {6TCHAR szbuf[ -];7 lpvoid lpMsgBuf;8DWORD DW =GetLastError ();9FormatMessage [1] (TenFormat_message_allocate_buffer |Format_message_from_system, One NULL, A DW, - makelangid (lang_neutral, Sublang_default), -(LPTSTR) &lpMsgBuf, the 0, NULL); - wsprintf (Szbuf, -_t ("%s error message (Error code =%d):%s"), -_t ("CreateDirectory"), DW, lpmsgbuf); + LocalFree (LPMSGBUF); - //The output hint.  + OutputDebugString (szbuf); A } at}

3 API:

GetLastError (),

FormatMessage (),

LocalFree ();
