Q:Most reasonable OS Layer Access?

Q:Most reasonable OS Layer Access?

[Michael Erdmann]

Dear all,

i need to create/delete directories, stop processes etc
from Ada 95. I am wondering what the most reasonable way
is to do such things (e.g. using florist or is there something
simpler available)?


Thanks in advance,
   Michael

These operations are all operating system specific, so you will need to
specify the OS before we can be of further assistance.

Although Florist would be neat to use, I have found GNAT specific 
packages such as Gnat.OS_Lib and Gnat.Directory_Operations for file and 
directory access quite adequate.
For processes, well, perhaps Gnat.Expect? If not, just import kill, 
spawn (in Gnat.OS_Lib btw) and other functions from the OS library. 
Might be a bit too platform specific compared to Florist, but simpler...

Linux and like to keep it portable towards Windows XP.

If Win32 based then you could try Ada0Y.Directories from my
web page @ http://www.martin.dowie.btinternet.co.uk/.
This is an implementation of the proposal for Ada0Y (AI-248, see
http://www.ada-auth.org/cgi-bin/cvsweb.cgi/AIs/AI-00248.TXT).

Thanks for your ideas,

i have decided to use the GNAT libraries and i will build a 
shell around it providing my the services i need.
