CallLibrary Properties Table

Property ID	Short Name (English)	Description	R/W	RTE
636D40D	AbortCallback	Sets or returns the name of the abort callback function that LabVIEW calls.	R/W
636D405	AllowPrealloc		R/W	X
636D403	AnyThread	Indicates whether the function is reentrant.	R/W
636D402	CallConvention	Uses the calling conventions to call libraries. Valid values include 0 (C Call) and 1 (stdcall (WINAPI)).	R/W
636D40A	DynamicLib	Sets the Call Library Function Node, in write mode, to execute with the library path you specify. In read mode, this property returns whether LabVIEW configures the Call Library Function Node to load the library dynamically. With the dynamic library property set in write mode, the library loads when LabVIEW executes the node. When you wire a different path, the Call Library Function Node unloads the previous library and loads the new library. When you wire a NULL path, the Call Library Function Node unloads the previous library and loads the NULL path in the same way.	R/W
636D40E	ErrorCheckingLevel	Sets or returns the error level for the Call Library Function Node. Valid values include 0 (maximum), 1 (default), and 2 (disabled).	R/W
636D401	FuncName	Sets or returns the name of the function you configure the Call Library Function Node to call.	R/W
636D408	InputTerms	Returns a 1D array of references to the input parameters.	R	X
636D400	LibPath	Specifies the path to the DLL or shared library the Call Library Function Node calls.	R/W
636D406	NIValidated		R/W	X
636D407	OutputTerms	Returns a 1D array of references to the output parameters.	R	X
636D409	ParamInfo	Sets or returns an array of clusters with information for the parameters of a function. Each cluster in the array represents a parameter of the function, starting with the return value. The property only returns the fields relevant to the parameter type. For example, if the parameter type is a numeric, the property returns a value to the Param Passing element but not to the Array Passing element.	R/W	X
636D40B	ReserveCallback	Sets or returns the name of the reserve callback function that LabVIEW calls.	R/W
636D40C	UnreserveCallback	Sets or returns the name of the unreserve callback function that LabVIEW calls.	R/W
