Changing File Attributes using the MS C RTL

[Wylbur]

Hi all;

I'm trying to find a function from within the Microsoft Run-Time Library
for changing the attributes for a given file. Specifically, the attributes
that follow:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
_A_ARCH
Archive. Set whenever the file is changed and cleared by the BACKUP command. Value: 0x20.

_A_HIDDEN
Hidden file. Not normally seen with the DIR command, unless the /AH option is used. Returns information about normal files and files with this attribute. Value: 0x02.

_A_NORMAL
Normal. File has no other attributes set and can be read or written to without restriction. Value: 0x00.

_A_RDONLY
Read-only. File cannot be opened for writing and a file with the same name cannot be created. Value: 0x01.

_A_SUBDIR
Subdirectory. Value: 0x10.

_A_SYSTEM
System file. Not normally seen with the DIR command, unless the /A or /A:S option is used. Value: 0x04.

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

I am able to get the above attributes using the _find functions
(findfirst and findnext):

Now that I have them, I want to be able to change them.

The function "chmod" doesn't cover all of the above attributes.

The system command "Attrib" does cover all of the attributes that
I would like to change.

I could use the methods within the System::IO namespace of the
.NET Framework, and I will do that if I have no other alternative.

My question is: Does anyone know of any alternatives?

What about system services interrupts?
(I am not afraid to code in assembly language.)

Thanks!!!

Forget that. Use the Platform SDK function SetFileAttributes.

Hi kbw;

This is what I have had to do.

I'm surprised that there are no RTL functions for doing this.

Thanks for the response!!!

There are not standardized in the C/C++ RTL because file attributes are file system specific.
