Detailed Description

Main library header file for CUDPP hash tables. Defines public interface.

cudpp_hash.h

The CUDPP public interface is a C-only interface to enable linking with code written in other languages (e.g. C, C++, and Fortran). While the internals of CUDPP are not limited to C (C++ features are used), the public interface is entirely C (thus it is declared "extern C").

Enumerator
CUDPP_BASIC_HASH_TABLE	Stores a single value per key. Input is expected to be a set of key-value pairs, where the keys are all unique.
CUDPP_COMPACTING_HASH_TABLE	Assigns each key a unique identifier and allows O(1) translation between the key and the unique IDs. Input is a set of keys that may, or may not, be repeated.
CUDPP_MULTIVALUE_HASH_TABLE	Can store multiple values for each key. Multiple values for the same key are represented by different key-value pairs in the input.
CUDPP_INVALID_HASH_TABLE	Invalid hash table; flags error if used.
