Begin 

Returns the location of the first interface from a list.

Syntax  

adlx_uint    Begin ()

Parameters 

N/A

Return Value 

If the list is not empty it returns the location of the first interface in the list.

If the list is empty the returned location is same as the location returned by End .

Remarks 

The returned location is valid if it is less than the location returned by End . The Begin is used in combination with End for parsing the list sequentially from the beginning to the end.

If the list is empty, Begin and End return the same location.
