Hi,
thanx for the responses.
i will make my requirement more clear using an example.
Imagine my C/C++ file looks like this :
//*************** FILE BEGINS**************
int a;
void setI()
{
a = 10;
}
int returnI()
{
return a;
}
void main()
{
setI();
// : Pseudo call to a perl file. This is what i need to know
system("source test.pl");
}
// : C file ends
NOw, i dont know perl syntax much , but this i how i imagine test.pl woulod look like
**************** test.pl file ****************
use ....
....
....
my $x
$x = getI() // : This is the call to the C function.
print($x);
.....
.....
****************** end ***************************
I want to build the C code as an executable so that on running the main
function , that value 'a' should be set , then the perl file should be
sourced which calls the getI() function and prints the returned value.
I have tried using the Inline option provided in Perl. It works
for small programs like above , but it requires that i right the C code in the perl file itself. I want a way to avoid writing the C code in the perl file
i just want some way that an interface to an existing code / data structure can be created.
Thanks,
Abhinav
