Creates or opens a file.

Parameters

FileHandle	A variable that receives the file handle.
FileName	The Win32 file name.
DesiredAccess	The desired access to the file.
FileAttributes	File attributes applied if the file is created or overwritten.
ShareAccess	The file access granted to other threads. `FILE_SHARE_READ` Allows other threads to read from the file. `FILE_SHARE_WRITE` Allows other threads to write to the file. `FILE_SHARE_DELETE` Allows other threads to delete the file.
CreateDisposition	The action to perform if the file does or does not exist. `FILE_SUPERSEDE` If the file exists, replace it. Otherwise, create the file. `FILE_CREATE` If the file exists, fail. Otherwise, create the file. `FILE_OPEN` If the file exists, open it. Otherwise, fail. `FILE_OPEN_IF` If the file exists, open it. Otherwise, create the file. `FILE_OVERWRITE` If the file exists, open and overwrite it. Otherwise, fail. `FILE_OVERWRITE_IF` If the file exists, open and overwrite it. Otherwise, create the file.
CreateOptions	The options to apply when the file is opened or created.

		_Out_opt_ PULONG	CreateStatus
	)

Creates or opens a file.

Parameters

FileHandle	A variable that receives the file handle.
FileName	The Win32 file name.
DesiredAccess	The desired access to the file.
FileAttributes	File attributes applied if the file is created or overwritten.
ShareAccess	The file access granted to other threads. `FILE_SHARE_READ` Allows other threads to read from the file. `FILE_SHARE_WRITE` Allows other threads to write to the file. `FILE_SHARE_DELETE` Allows other threads to delete the file.
CreateDisposition	The action to perform if the file does or does not exist. `FILE_SUPERSEDE` If the file exists, replace it. Otherwise, create the file. `FILE_CREATE` If the file exists, fail. Otherwise, create the file. `FILE_OPEN` If the file exists, open it. Otherwise, fail. `FILE_OPEN_IF` If the file exists, open it. Otherwise, create the file. `FILE_OVERWRITE` If the file exists, open and overwrite it. Otherwise, fail. `FILE_OVERWRITE_IF` If the file exists, open and overwrite it. Otherwise, create the file.
CreateOptions	The options to apply when the file is opened or created.
CreateStatus	A variable that receives creation information. `FILE_SUPERSEDED` The file was replaced because `FILE_SUPERSEDE` was specified in CreateDisposition. `FILE_OPENED` The file was opened because `FILE_OPEN` or `FILE_OPEN_IF` was specified in CreateDisposition. `FILE_CREATED` The file was created because `FILE_CREATE` or `FILE_OPEN_IF` was specified in CreateDisposition. `FILE_OVERWRITTEN` The file was overwritten because `FILE_OVERWRITE` or `FILE_OVERWRITE_IF` was specified in CreateDisposition. `FILE_EXISTS` The file was not opened because it already existed and `FILE_CREATE` was specified in CreateDisposition. `FILE_DOES_NOT_EXIST` The file was not opened because it did not exist and `FILE_OPEN` or `FILE_OVERWRITE` was specified in CreateDisposition.
