OSAGetScriptingComponentFromStored

You can use the OSAGetScriptingComponentFromStored routine to get the subtype code for a scripting component that created a storage descriptor record.

FUNCTION OSAGetScriptingComponentFromStored
               (genericScriptingComponent: ComponentInstance;
                scriptData: AEDesc;
                VAR scriptingSubType: ScriptingComponentSelector)
                : OSAError;

genericScriptingComponent

A component instance for the generic scripting component, created by a prior call to the Component Manager function OpenDefaultComponent or OpenComponent (see page 10-4).

scriptData

Either a generic storage descriptor record or a component-specific storage descriptor record.

scriptingSubType

The function returns, in this parameter, a subtype code identifying the scripting component that created the descriptor record specified by the scriptData parameter.

DESCRIPTION

The OSAGetScriptingComponentFromStored function returns, in the scriptingSubType parameter, the subtype code for the scripting component that created the script data specified by the scriptData parameter.

The generic scripting component automatically identifies the appropriate scripting component for you when you use it to call OSALoad. By calling OSAGetScriptingComponentFromStored, you can determine, without loading a script, which scripting component created the script data.

RESULT CODES
