HANDLE CreateFile(
LPCTSTR lpFileName,
DWORD dwDesiredAccess,
DWORD dwShareMode,
LPSECURITY_ATTRIBUTES lpSecurityAttributes,
DWORD dwCreationDispostion ,
DWORD dwFlagsAndAttributes,
HANDLE hTemplateFile );
Parameters
lpFileName
Pointer to a null-terminated string that specifies the name of the object (file, communications resource, disk device, console, or directory) to create or open.
If *lpFileName is a path, there is a default string size limit of MAX_PATH characters. This limit is related to how the CreateFile function parses paths.
When lpFileName points to a communications resource to open, the developer must include a colon after the name. For example, specify "COM1: " to open that port.
dwDesiredAccess
Specifies the type of access to the object. An application can obtain read access; write access, read-write access, or device query access. This parameter can be any combination of the following values.
