Well, since I do not have open solaris setup to test this I used 5.8, might be
it behave the same in open source as well...then its justified to post it here
:)
Anyway, below is my code (As an experiment I did this in linux and result
matched my expectation)
#include <iostream>
#include <string>
// Required by for routine
#include <sys/types.h>
#include <unistd.h>
using namespace std;
int globalVariable = 2;
main()
{
string sIdentifier;
int iStackVariable = 20;
pid_t pID = vfork();
if (pID == 0) // child
{
// Code only executed by child process
sIdentifier = "Child Process: ";
globalVariable++;
iStackVariable++;
cout << sIdentifier;
cout << " Global variable: " << globalVariable;
cout << " Stack variable: " << iStackVariable << endl;
_exit(0);
}
else if (pID < 0) // failed to fork
{
cerr << "Failed to fork" << endl;
exit(1);
// Throw exception
}
else // parent
{
// Code only executed by parent process
sIdentifier = "Parent Process:";
}
// executed only by parent
cout << sIdentifier;
cout << " Global variable: " << globalVariable;
cout << " Stack variable: " << iStackVariable << endl;
exit(0);
}
