Hi,
I am very interesting in Parrot embedding system it is part of my diploma
project "The assessment of appropriateness of using virtual machines to
decode packets". I`d like to ask how to pass arguments from C to Parrot
subroutines? What is the best a most comfortable way? I will appreciate some
examples.
take a look at docs/embed.pod -- it has documentation on the functions
you'd be using, in particular the Parrot_call_sub family of functions.
you pass the subroutine name, a type signature for the arguments, and the
arguments themselves.
you can find examples in t/src/extend.t and t/src/embed.t, as well as
real-world usage in the mod_parrot source in src/parrot_util.c
(svn repo at https://svn.perl.org/parrot-modules/mod_parrot/trunk/)
I am also thinking about which data structure should I use to store/represent
packet in PIR. If you have had ever meet this problem or solution pls let me
know. Thanks.
you can store the raw data in a PMC (very simple if you pass it as an
argument from C), and/or your could break it out into an object (also a
PMC). you can do this from C or PIR. it all depends on how and where you
plan on using the data.
btw: this is my first mailing list ever so pls have a patience with me
welcome!
With best regards,
Radovan
