Hi,
Thanks for your quick suggestion. I grazed over the 'constant' pragma.
From the given link,
My main aim is to use the constant in a 'if' condition.
To elaborate, my scenario is:
Then that is not strictly a "constant".
Why do you have to do it like that? You can take a reference of a filehandle and then use it with the slurp ( <> ).
in the header file orville.h, outside of the #ifdef #endif , there is the following
#define JOB_CONTROL /* support job-control */
As you can see, the JOB_CONTROL macro has no value associated with it. Here is what I go when I ran grep on the entire source code.

hi
I have a perl script from which I call a shell script and pass mail variable to it.
The mail works fine if I give 1 recipient but fails for multiple.
conv.pl:-
$mialing = "anu\@abc.com"
rest.sh $mialing
rest.sh
mail -s "hi" $1
This works fine
But I need to define multiple... (2 Replies)

Hi,
Is it possible in perl to have a hash defined with variables as theirs key values, like:
%account = ('username' => 'boy', 'password' => $password);
Thanks (1 Reply)
Hey everyone. So I'm looking at a few C programming resources, and it seems, by convention how you should write and define a function, is first declare it's existence before your main...then call it somewhere in your main, and then define after, at the end of the program? Is this necessary? I mean... (7 Replies)

coro::makemaker
MakeMaker(3pm) User Contributed Perl Documentation MakeMaker(3pm)NAME
Coro::MakeMaker - MakeMaker glue for the XS-level Coro API
SYNOPSIS
This allows you to control coroutines from C/XS.
DESCRIPTION
For optimal performance, hook into Coro at the C-level. You'll need to make changes to your "Makefile.PL" and add code to your "xs" / "c"
file(s).
WARNING
When you hook in at the C-level you can get a huge performance gain, but you also reduce the chances that your code will work unmodified
with newer versions of "perl" or "Coro". This may or may not be a problem. Just be aware, and set your expectations accordingly.
HOW TO
Makefile.PL
use Coro::MakeMaker qw(coro_args);
# ... set up %args ...
WriteMakefile (coro_args (%args));
XS
#include "CoroAPI.h"
BOOT:
I_CORO_API ("YourModule");
API
This is just a small overview - read the Coro/CoroAPI.h header file in the distribution, and check the examples in EV/ and Event/*, or as a
more real-world example, the Deliantra game server (which uses Coro::MakeMaker).
#define CORO_TRANSFER(prev,next) /* transfer from prev to next */
#define CORO_SCHEDULE /* like Coro::schedule */
#define CORO_CEDE /* like Coro::cede */
#define CORO_CEDE_NOTSELF /* like Coro::cede_notself */
#define CORO_READY(coro) /* like $coro->ready */
#define CORO_IS_READY(coro) /* like $coro->is_ready */
#define CORO_NREADY /* # of procs in ready queue */
#define CORO_CURRENT /* returns $Coro::current */
#define CORO_THROW /* exception pending? */
#define CORO_READYHOOK /* hook for event libs, see Coro::EV */
#define CORO_SV_STATE(coro) /* returns the internal struct coro * */
#define CORO_EXECUTE_SLF(cv,init,ax) /* execute a schedule-like function */
#define CORO_EXECUTE_SLF_XS(init) /* SLF in XS, see e.g. Coro::EV */
