Hello C natives
What is the most straightforward way to have a running C program send data (global variables) to a PD patch for real time control (say a vector of ten floats, 80 times per second), means : what names for fonctions (procedures) in C, and what objects in PD (netreceive ? dumposc ?), all of this on windows... Tks JM
PS Although i wrote thousands of lines of C++ in my young age, i dont remember ANYTHING about it now, except semi columns and {braces} or so.
there already is a c program for sending data to pd over network, it's called pdsend.exe

Hi,
you could send your data to stdout, then pipe it through command "pdsend", and finally get it back in Pd with [netreceive] ; but are you working on a Unix-like sytem ?

all of this on windows...
sorry... But actually it may work on windows too ?

The source for pdsend is in src/u_pdsend.c in any vanilla pd setup. The easiest thing would be to incorporate that into your program by replacing the argument list with a buffer containing a string with the values to be sent.

… thanks for these elements. basically, my patches are on MacOs since decades (...), and for a specific experiment I’ve to collaborate with a guy working in C on windows, who (this person) does not know anything about pd : so the question was
- is there a function / procedure / .exe somewhere in C whose name i could pronounce to this guy so that he gets a way into the subject, and, on my side, by the way, to which object would the data be sent in pd .. all this for a low control rate from C to pd approx vector 10 floats 80 ps.
but maybe things are not so simple :) and maybe i can juste say to send from C to the « network » or kind of internal machine bus (no hint how this works on windows though !) hmm :) jm

try to use osc .
it makes your program run on a protocol, and makes it modular more easily ( adress another machine on the network, for instance)

look for an osc library for c++ , there are many
i had an experience of this kind , this library was used
oscpack -- Open Sound Control packet manipulation library http://www.audiomulch.com/~rossb/code/oscpack

i would recommend liblo [1] instead. it seems to be the most commonly used library these days. it is also more actively developed than oscpack.
liblo states that it is an OSC-implementation for "POSIX systems" (which w32 is not), but afaik it does work on w32.
