VECTORENUMGROUPSPROC Function

#include "lvkrn.h"

L_INT pEXT_CALLBACK YourFunction(pVector, pGroup, pUserData)

pVECTORHANDLE pVector;	/* pointer to a vector handle */
pVECTORGROUP pGroup;	/* pointer to a vector group */
L_VOID *pUserData;	/* pointer to additional parameters */

Processes each vector group enumerated by the L_VecEnumGroups function.

Parameter	Description
pVector	Pointer to the vector handle that contains the groups to enumerate.
pGroup	Pointer to the vector group being processed.
pUserData	A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of the calling function.)
	Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

The L_VecEnumGroups function calls the callback function as it gets the handle of each vector group.
