Data forking process.

Code:
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main()
{
        pid_t pID;
        int i;

        for (i = 0; i < 3; i++)
        {
                pID = fork ();

                if (pID == 0)
                {
                        printf ("Value of i --> %d \n", i);
                        switch (i)
                        {
                                case 0:
                                        func0 (i);
                                        break;
                                case 1:
                                        func1 (i);
                                        break;
                                case 2:
                                        func2 (i);
                                        break;
                        }
                }
        }

        return 0;
}


My intention is to execute the function depending on the case. I dont want to wait for the first process to complete. I used fork. Can u help me out in solving this. My requirement is very much similar to multithreading.

FBB::mlm(3bobcat)					      OFoldStream manipulator						 FBB::mlm(3bobcat)

NAME
FBB::mlm - Manipulator modifying left margins of OFoldStream objects SYNOPSIS
#include <bobcat/ofoldstream> or #include <bobcat/ofoldstreambuf> Linking option: -lbobcat DESCRIPTION
The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request then left margin 0 will silently be used. Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of tab-characters that will be added to the left margin. The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at the next word inserted into that line (cf., the example section below) A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer. NAMESPACE
FBB All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB. INHERITS FROM
- CONSTRUCTOR
o mlm(int addValue): The standard copy constructor is available. MEMBER FUNCTIONS
There are no public or protected member functions in this class. EXAMPLE
#include <iostream> #include <bobcat/ofoldstream> using namespace std; using namespace FBB; int main() { OFoldStream out(cout, 0, 80); out << "hello world (left margin is 0)" << mlm(4) << " " "this uses a 4 character wide left margin " << mlm(-10) << flush << "left margin -6 changed to 0, active on this line "; return 0; } FILES
