auth2table

AUTH2TABLE(3)						     AUT STRUCTURE DEFINITIONS						     AUTH2TABLE(3)

NAME

       auth2table - hash table structure

DESCRIPTION

       The auth2table structure is used to describe an hash table with two keys.

       The declarations needed to work on auth2table are available in the header file "/labo/include/aut101.h", where '101' is the actual aut ver-
       sion.

       The following C structure supports the description of an hash element :
		typedef struct auth2table
		{
		  auth2elem *TABLE;
		  long	    TABLE_SIZE;
		  long	    NUMBER_ELEM;
		  long	    NUMBER_ADD;
		  long	    NUMBER_SCAN;
		  long	    NUMBER_DEL;
		  long	    NUMBER_STRETCH;
		} auth2table;

       TABLE
			    TABLE is the hash element array.

       TABLE_SIZE
			    TABLE_SIZE is the size of the hash table.

       NUMBER_ELEM
			    NUMBER_ELEM is the number of element in the hash table.

       NUMBER_ADD
			    NUMBER_ADD is the number of added elements.

       NUMBER_SCAN
			    NUMBER_SCAN is the number of scans to find an element.

       NUMBER_DEL
			    NUMBER_DEL is the number of deleted elements.

       NUMBER_STRETCH
			    NUMBER_STRETCH is the number of hash table stretch.
