reading NTFS Share permission - how to interpret SHARE_INFO_2.Permissions flag

[C# Programming]

hi i am trying to read NTFS share permission. Imported

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
protected struct SHARE_INFO_2
{
[MarshalAs(UnmanagedType.LPWStr)]
public string NetName;
public ShareType ShareType;
[MarshalAs(UnmanagedType.LPWStr)]
public string Remark;
public int Permissions;
public int MaxUsers;
public int CurrentUsers;
[MarshalAs(UnmanagedType.LPWStr)]
public string Path;
[MarshalAs(UnmanagedType.LPWStr)]
public string Password;
}


According to MSDN, Permissions include ACCESS_READ, ACCESS_WRITE, ... etc but the document doesn't tell you the "Integer" value of these constants. Where can I find the C++ header file where these constants are defined? I need them so I can convert integer value "Permissions" into human readable message.

Thank you!
