Thread: exec a bash script

hello!

I'm writing a C++ program and I use fork() and execl to call a bash script.My .cpp communicates with the script with a pipe in which the script writes data and then the .cpp reads them.I don't think my script is ever executed the way I'm doing it...

Code:

        int pid;
	int res = mkfifo (pipeName, 0666); 
	if (res < 0) {
		perror("Error creating the named pipe");
		exit (2);
	}
	
	pid=fork();
	if(pid<0)
	{
		cerr << "Failed to fork" << endl;
		exit(1);
	}

	if(pid==0){
		
		execl("./bbb","bbb",argv[1],pipeName,NULL);
		exit(0);
	}

where pipeName is the name of the pipe .cpp and bash script communicate with,argv[1] is just a string,bbb is the name of the script

In my script when I want to write something to the pipe I do

Code:

echo $var2 >> $2

where $2 is the name of the pipe the script got when called.

When I run it it seems to meet a deadlock so I figured maybe the script is never called...
Any ideas?
