TSR programming- alternative of keep()

Hello, in 16 bit DOS programming, keep() is used to resident a program in memory, but in 32 bit / 64 bit C compiler, how can I use this?If keep() does not work, then what is the alternative function that works? Please help

In Windows you write the program as a service. In Unix/Linux you write it as a daemon. For Windows see https://msdn.microsoft.com/en-us/lib...=vs.85%29.aspx

Thank you Sir
