hello
i'm writing a program in c++ and i'm using linux.
i use fork() in order to create a process and then i want to wait for the child process
to finish so its something like that:
pid=fork();
if(pid<0)
{
cerr << "Failed to fork" << endl;
exit(1);
}
if(pid==0){
/*do what you have to do*/
exit(0);
}
int status;
wait(&status);the thing is that it doesnt accept this syntax of wait()
which is really strange as in C works fine.
can anybody tell me whats wrong?
Could you post the exact error message you are getting, please?
it tells me that "status" was previously declared although i havent declared it anywhere. maybe its something wrong with the libraries included.these are the libraries i include below:
#include<stdio.h>
#include <iostream>
#include<string.h>
#include <poll.h>
#include <signal.h>
#include <fcntl.h>
#include <ctype.h>
#include <sys/types.h>
#include <fstream>
#include <sys/times.h>
#include <unistd.h>
I would venture to guess that one of those libraries has declared 'status as a variable or function. Try changing the name to something like 'mystatus' or 'waitstatus' and see if you still get an error.
