After the regular copy routine (I assume you've already done this
part), you need to explicitely set the attributes yourself.
You do this by grabbing a copy of the source files info block
(with the Examine() command) and altering just three attributes
of the target file - the comment, the date and the protection
flags. There are three functions in the dos.library that allows
you to do this - SetComment(), SetFileDate() and SetProtection().
A simple function to do this might be written thus,
void
setAttributes (STRPTR target_file, struct FileInfoBlock * source_file_fib)
{
SetProtection (target_file, source_file_fib->fib_Protection);
SetFileDate (target_file, source_file_fib->fib_Date);
SetComment (target_file, source_file_fib->fib_Comment);
}
It may be worth checking for success as not all file systems
support Amiga style protection and comments
You may also consider supporting the multi-user elements, owner
and group IDs, but you'll need an appropriate API for that such
as MUFS.
