vxWorks Directory Browsing

vxWorks Directory Browsing

[matthew.gaehring]

I need to be able to search a particular directory and pull in a
listing of all subdirectories that exist within that directory.  I am
using AdaMULTI 2000 compiling to run on a vxWorks 5.4 platform.  I know
GNAT has a nice and easy package to handle all that, unfortunately I
have no choice but to use AdaMULTI, can anyone help me out with a
method that would work?

Sorry to post again, but I thought I should also mention that I coding
in Ada95.

For VxWorks, I'd be tempted to try and port the POSIX bindings from

http://libre.act-europe.fr/GNAT/

specifically

http://libre.act-europe.fr/GNAT/3.15p/florist-3.15p-src.tgz

Thanks for the reply, I wish that I could do just that, but
unfortunately I am limited to only using what is available within
Ada95, AdaMULTI, and vxWorks.  My employer is extremely restrictive in
that I can only use the specific tools that are contracted to this
program.

I'm willing to resort to vxWorks calls if there is no way within Ada to
do the directory browsing, if that's what I'm left with does anyone
have any suggestions how to do that in Ada?

In that case lookup the thin binding for "dirLib.h" that should be 
provided with AdaMULTI. This is a POSIX library and one that florist 
access - so you will be largely re-writing that bit of florist!

Standard package "Ada.Directories" is not Ada95 but Ada2005. There are 
Win32 and Linux versions around but I don't of a VxWorks port.

What do you mean by "available within Ada95"?  The
ability to bind to OS calls (pragma Import) is "within
Ada".  And since that's within Ada, what's the
difference between writing the binding yourself, or
using a binding someone else has written? 

Besides, anything "in Ada" will ultimately be wrapped
around an OS call anyway.  

Also, you could always use an existing binding as a
template to make your own.

But I would be slightly wary of licensing issues. The GMGPL that GNAT
code comes under says you can compile or instantiate it, it doesn't
say you can copy chunks of it into your own source tree ...

Well, I didn't say copy it.  I said, "use it as a
template".  Maybe I should have said, "use it as an
example".  But, I know what you mean.
