I'm trying to use NodeJS with a C program to http://en.wikipedia.org/wiki/Setvbuf for JS files using Fork().

My program.c :

int readTabStr(int k)
{
char * tabString[] = {"p1.js","p2.js","p3.js","p4.js"};
int taille = sizeof(tabString)/sizeof(char);
int i;
    for(i=0; i<taille; i++)
    {
        if (fork() == 0)
        {
            execlp("node","node", tabString[i], NULL);
        }
        else
        {
            wait(NULL);
        }
    }
return 0;
}

I'm using this JS file to launch the C file:

var FFI = require("../../lib/ffi");

var test = new FFI.Library("./readTab", {
"readTabStr": ["int", ["int" ]]  
});

var resultat = test.readTabStr(0);

The problem is that after executing the p1.js, p2.js, p3.jsn p4.js. I get 4 error messages :

node.js:116
throw e; // process.nextTick error, or 'error' event on first tick
^

Error: Cannot find module '/home/fighter/Documents/ffi/kerrighed/execlp/��$[]�U

at Function._load (module.js:245:25)
at Array.<anonymous> (module.js:402:10)
at EventEmitter._tickCallback (node.js:108:26)

Any ideas?

Solved,

The problem was 

 int taille = sizeof(tabString)/sizeof(char);

I should do : 

int taille = sizeof(tabString)/sizeof(char*);

Thanks anyway.

  • Related to your just removed question: see http://jsfiddle.net/Lepfsm9r/1/. Not sure if it is any good, but probably will give you some jump-start. – Wiktor Stribiżew Jun 25 '18 at 16:03
