Customizing Functions Using Options
API functions are customized by setting options. Each function that yo u can customize
has an options handle parameter, which refers to an options structure that is internal to
RSC/MP. An options structure contains option values that are referred to by their
corresponding option selectors. For example, PATHMON_NAME is an option selector
(see Appendix D, API Option Definitions, for a complete list). An option selector and its
value are referred to collective ly as an option. You should create and set options
before making calls to the corresponding function.
You must create an options structure by using the RscCreateOptions function call.
Options structures are subsequently referred to by the options handle returned from
the RscCreateOptions function.
To set individual options programmatically, use the RscSetOption function call. To load
a set of options from an existing disk file, use the RscLoadOptions function call.
