In Win32 layer, we often meet ERROR_PATH_NOT_FOUND
, ERROR_NAME_NOT_FOUND
.
When does WinAPI(eg CreateFileW, RemoveDirectoryW)
return these values? And What's the difference?
If I write a file system driver, when do I set STATUS_OBJECT_PATH_NOT_FOUND
or STATUS_OBJECT_NAME_NOT_FOUND
?
How do you determine?
I'm so confused. Is there anyone who can explain clearly?
Or are there any documents explain this? I couldn't find them.
Thanks in advance.
ERROR_NAME_NOT_FOUND
is not a standard Win32 API error code. Typical errors returned by file related APIs that take a file name are ERROR_FILE_NOT_FOUND
and ERROR_PATH_NOT_FOUND
. The best way to figure out what error code to return is use a WDK sample as a guide. The cdfs sample's create.c
source code file for example. It returns STATUS_OBJECT_PATH_NOT_FOUND
if it cannot locate a directory, STATUS_OBJECT_NAME_NOT_FOUND
if it cannot locate a file.
