DESCRIPTION
When process is copied by fork() system call, ndrx_atfork_parent() shall be executed by parent process after the fork call. This ensures that Enduro/X sub-systems for parent process returns to normal operations after the parent’s ndrx_atfork_prepare() and fork() calls.
At given time function does some logic only if System V IPC is used, for others IPC transports it does not any logic, but this fact is subject of change, and in future releases some other tasks might be required to be done by Enduro/X after process forking, thus it is recommended to use ndrx_fork(), call manually ndrx_atfork_parent() or register it with pthread_atfork()
