There's always a way. Depends on what exactly you had in mind. If you just
want to invoke a program, here's some code cut from a batch of utilities on
my web page (see: http://www.mcondic.com/):
with Interfaces.C;
procedure UTIL.Perform_System_Command (
Command : in String ;
Wait : in Boolean := True ;
Success : out Boolean) is
--
Return_Code : Integer ;
--
function Sys (
Item : in Interfaces.C.Char_Array) return Integer ;
pragma Import (C, Sys, "system") ;
--
package C renames Interfaces.C ;
--
begin
--
if (Wait) then
Return_Code := Sys (
Item => C.To_C ("ksh -c " & '"' & Command & '"'));
else
Return_Code := Sys (
Item => C.To_C ("ksh -c " & '"' & Command & " &" & '"'));
end if ;
--
if (Return_Code /= 0) then
Success := False ;
else
Success := True ;
end if;
--
end UTIL.Perform_System_Command ;
If you want to actually interface to some OS service that is normally got to
via a subprogram call, then perhaps if you post the call (I presume it is
written in C?) we could help you with the appropriate pragmas, linkage, etc.
A Solution Does Exist, but you might need to be a little more specific.
