Parameter

Description

pVector

Pointer to the vector handle that contains the layers to enumerate.

pLayer

Pointer to the vector layer 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.

SUCCESS

The function was successful.
