MapInitHashTable
================

.. us.tag  MapInitHashTable NOTREADYENGLISH Map_Set

:ref:`MapInitHashTable` initializes the hash table.

.. function::  bool = MapInitHashTable(hMap, nSize)

.. us.return

**Return Value**

If the function succeeds, the return value *bool* is TRUE (1); otherwise it is
FALSE (0).

.. us.params

**Parameters**

.. uparam:: hMap

   *hMap* identifies the map.

.. uparam:: nSize

   *nSize* For best performance, the hash table size should be a prime number. To
   minimize collisions the size should be roughly 20 percent larger than the
   largest anticipated data set. Example-Prime-Numbers: 11, 13, 17, 53, 101, 211,
   307, 401, 503, 601, 701, 809, 907, 5003, 9973.
