Missing declare's in WIN32API.INC

[Clay Clear]

I was trying to use this one API Call, then discovered that it's
not in the Win32api.inc file. The DECLARE itself I could figure out
from the Win32.hlp description. However, the FUNCTION uses an
equate that is also not in the INC file, and I have NO way of
knowing what it should be.

The API Function is: GetFileAttributesEx()

The Equate is: GET_FILEEX_INFO_LEVELS

The INC is also missing a required TYPE: WIN32_FILE_ATTRIBUTE_DATA

Any help would be greatly appreciated!

Thanks in advance.

According to my notes, this is a NT-only API which is probably why it is not int he WIN32API.INC file.

It should look something like this:

DECLARE FUNCTION GetFileAttributesEx LIB "KERNEL32.DLL" ALIAS "GetFileAttributesEx" (lpfilename AS ASCIIZ, BYVAL fIndoLevelId AS LONG, lpFileInformation AS ANY) AS LONG

(It may need an "W" at the end of the ALIAS name.

More later if I can find the UDT info.

Lance,

Thanks for your reply. You don't have to find the info, then, as
I am running a Win98SE machine. I messed up - I thought when the
Win32.hlp says, "New - Windows NT", that it meant that it were
new TO NT, but had existed for other OS's. Now I know that it
means that it's NT-specific. Shows you how multifaceted the
English language is. <chuckle>

Thanks, anyway!

Regards,

P.S. I'll use GetFileInformationByHandle, instead.

Clay,

You can use the 'Quick Info' button in Win32.hlp to tell which platform the function in question is supported.

That needs to be ALIAS "GetFileAttributesExA". The function is available
under Windows 98 and later, and NT 4.0 and later. The only documented
"info level" is 0 (zero), which returns a value of:

TYPE WIN32_FILE_ATTRIBUTE_DATA
  dwFileAttributes AS DWORD
  ftCreationTime AS FILETIME
  ftLastAccessTime AS FILETIME
  ftLastWriteTime AS FILETIME
  dwVolumeSerialNumber AS DWORD
  nFileSizeHigh AS DWORD
  nFileSizeLow AS DWORD
END TYPE

Sadly, it's not possible to substitute a QUAD for the file size DWORDs,
as Microsoft put the DWORDs in the wrong order.

With some of the NT only API calls, maybe they can be included in WIN32API.INC, but have an #IF statement to lock them out if we don't need them.

It's on the longer-term plan...

There's no harm done in making the NT-only calls available in the
Win32API files: declarations don't use up resources. Trying to keep
track of which calls are available under which OSes is somewhat
futile, in any event-- an API may be tied, not so much to the OS,
as to the version of (say) Microsoft Internet Explorer or other
installed tools.

There are plans to break the include files into more convenient
modules in the future but, it's a massive job, and may not be soon
to come.

Might be convenient if PB added a new function:

MAKQD(lowDword, HiDword) - returns 64-bit integer with specified 32-bit entities as components

..which in this case would make the filesize

FileSize&& = MAKQD(X.filesizelow, X.FilesizeHigh)

I mean you already have MAKPTR, MAKDWD and MAKLNG...

It's on the wish list.
