NAME
authtable - hash table structure DESCRIPTION
The authtable structure is used to describe an hash table. The declarations needed to work on authtable 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 authtable { authelem *TABLE; long TABLE_SIZE; long NUMBER_ELEM; long NUMBER_ADD; long NUMBER_SCAN; long NUMBER_DEL; long NUMBER_STRETCH; } authtable; 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. SEE ALSO
