哪个结构体有问题,那里是要传递一个指针的,你可以设空,下面是C的代码,你参考一下 char *pcCommPort = "COM2";HANDLE hCom = CreateFile( pcCommPort, GENERIC_READ | GENERIC_WRITE, 0, // must be opened with exclusive-access NULL, // no security attributes OPEN_EXISTING, // must use OPEN_EXISTING 0, // not overlapped I/O NULL // hTemplate must be NULL for comm devices );
HANDLE CreateFile( LPCTSTR lpFileName, // pointer to name of the file DWORD dwDesiredAccess, // access (read-write) mode DWORD dwShareMode, // share mode LPSECURITY_ATTRIBUTES lpSecurityAttributes, // pointer to security attributes DWORD dwCreationDisposition, // how to create DWORD dwFlagsAndAttributes, // file attributes HANDLE hTemplateFile // handle to file with attributes to // copy );
char *pcCommPort = "COM2";HANDLE hCom = CreateFile( pcCommPort,
GENERIC_READ | GENERIC_WRITE,
0, // must be opened with exclusive-access
NULL, // no security attributes
OPEN_EXISTING, // must use OPEN_EXISTING
0, // not overlapped I/O
NULL // hTemplate must be NULL for comm devices
);
LPCTSTR lpFileName, // pointer to name of the file
DWORD dwDesiredAccess, // access (read-write) mode
DWORD dwShareMode, // share mode
LPSECURITY_ATTRIBUTES lpSecurityAttributes,
// pointer to security attributes
DWORD dwCreationDisposition, // how to create
DWORD dwFlagsAndAttributes, // file attributes
HANDLE hTemplateFile // handle to file with attributes to
// copy
);
这样试试,应该就不会错了
