IPC

IPC is a simple interprocess comunication library written in C. The IPC library wraps named pipes and works in posix compatible opperating systems (Support for windows is comming). The IPC library is based on sending messages through a connection and subscribing to message subjects on the other end of a connection.

Send message example:

#include <string.h>
#include "ipc.h"

int main (int argc char* argv[]){
    Connection* conn = connectionConnect("ExampleConnectionName", CONN_TYPE_SUB);
    char* data = "Example message data";
    Message* msg = messageCreate(data, strlen(data) +1);
    messageSetSubject(msg, "Example Subject");
    connectionSend(conn, msg);
    messagedestroy(msg);
    connectionDestroy(conn);
}

Recive message example:

#include "ipc.h"

int recieved = 0;
void callback(Message* msg){
    printf(msg->data);
    recieved = 1;
}

int main (int argc char* argv[]){
    Connection* conn = connectionCreate("ExampleConnectionName", CONN_TYPE_SUB);
    connectionSubscribe(conn, "Example Subject");
    connectionSetCallback(conn, callback);
    connectionStartAutoDispatch(conn);

    while(!recieved){
        usleep(100);
    }

    connectionStopAutoDispatch(conn);
    connectionClose(conn);
    connectionDestroy(conn);
}

There are also java, node.js and c++ bindings for the IPC library. The other bindings are similar to the C API. Refer to the Java, node.js or C++ examples.

Building

To build the whole project run "build.sh" from the root project directory.

To build only certain parts of the api go to the directory of the portion of the api that you want to build and run "make".

Refer to the README file in the node directory for instructions on building the node binding.
