[SOLVED] Standard I/O redirection in linux

[abhiram7]

Hi all

I am just gaining some understanding the fork system by the following simple program.
#include<unistd.h>
#include<stdio.h>
int main()
{
pid_t pid;
printf("Inside the Parent Process \n");
if((pid = fork())<0 )
printf("Oooops Error Occured in forking \n");
else if (pid ==0)
printf("Inside the child process and the process id is %d \n", getpid());
else
printf( "inside the parent process and the process id is %d \n",getpid());

}/*end of main */

when i run the program in terminal i get the expected output, but when i redirect the output to a file the file does not have the printf information of the child process.
my question is does linux perform standard I/O redirection for only the parent process and not the child process? or am i missing something.

can someone clarify!!
thanks

Never Mind, I found out my blunder in the program.

Out of curiosity, what was your solution? I'm looking at it and can't would be interested.
