solaris daemon question

solaris daemon question

[darren wilson]

I'm trying to write a simple daemon to run on a Sun E3500 running solaris
2.6.  Can anyone tell me how to issue command line unix statements such as
mv or cp and such from within an ada program?  I've been programming in
ada for a while, but have never done this.  Any help is appreciated.

Thanks in advance

Here's an interface to the "system" C library function:

with Ada.Characters.Latin_1;
with System;
function Execute_Shell_Command
           (The_Command : String) return Integer is
   function Execute
              (The_Command_Address : System.Address) return Integer;
   pragma Import (C, Execute, "system");
   The_Nul_Terminated_Command_String : constant String :=
     The_Command & Ada.Characters.Latin_1.Nul;
begin
   return Execute (The_Nul_Terminated_Command_String'Address);
end Execute_Shell_Command;
