Re: fork or printf problem

[Saugata Das Purkayastha <saugata@xxxxxxxxxxxxxx>]

Put, fflush(stdout), after the printf("Hello\n") statement. You will get
same result. The first "hello" is buffered and not printed and when it
forks, the child also gets a copy of that buffer. Thats why one extra
hello is printed.
