resourceConstructor

)

Add a constructor for a new resource type.

OsStatus newResource	(	const UtlString &	resourceType,
		const UtlString &	newResourceName,
		int	maxResourcesToCreate,
		int &	numResourcesCreated,
		MpResource *	resourcesCreated[]
	)		const

Create a new resource of given type.

Creates one or more resources as defined by the implementation of the named resource constructor (typically of different resource types as opposed to duplicates). Some resources are created in sets as they work together in some way. This interface allows the constructor to create multiple resources and assocate or initialize them together.

Parameters

[in]	newResourceName	- name to give the new resource, must be unique to the target flowgraph that this resource is to be inserted.
[in]	maxResourcesToCreate	- the size of the resourcesCreated passed in
[out]	numResourcesCreated	- the actual number of resource created and contained in the resourcesCreated array
[out]	resourcesCreated	- array containing the created resources.
