ZwCreateFile報錯0xC0000043，STATUS_SHARING_VIOLATION

在進行驅動開發時，調用ZwCreateFile報錯0xC0000043，STATUS_SHARING_VIOLATION，經過搜尋得知參數ShareAccess，指定“共享所有”的正确方法是FILE_SHARE_VALID_FLAGS，而不是0 。下面是幫助網頁

#define STATUS_SHARING_VIOLATION ((NTSTATUS)0xC0000043L)

If the file is local, you can call IoCreateFileEx and specify 

IO_IGNORE_SHARE_ACCESS_CHECK. Note that this doesn't do anything for a file 

on a network share.

Also, the proper way to specify "share all" is FILE_SHARE_VALID_FLAGS, not 0 

(which means "share none").
