main(int argc, char **argv)

earlier defination of this is

main(int argc, char **argv, char **environ)

Their are some alternatives, to use the getenv / setenv / putenv / clearenv to get the envrionment variables. As per naming conventions, data inside these should be in Name=Value pair. Their are various memory areas those you should be aware of

  2. Initialized Data Section
  3. uninitialized Data Section

EPFO has launched a facility to enable its subscribers to view their updated accounts online on real time basis without waiting for their annual PF account slips.
