library fully written from scratch in pure ANSI C. It is designed to offer

for C programmers common data structures with powerful algorithms, and hidden

implementation. Available structures are lists, queues, stacks, hash tables,

binary trees, binary search trees, red-black trees, 2D arrays, permutations

(description
|
|
"This library contains several hash-map implementations, similar in API
|
|
to SGI's @code{hash_map} class, but with different performance
|
|
characteristics. @code{sparse_hash_map} uses very little space overhead, 1-2
|
|
bits per entry. @code{dense_hash_map} is very fast, particulary on lookup.
|
|
@code{sparse_hash_set} and @code{dense_hash_set} are the set versions of these
|
|
routines. All these implementation use a hashtable with internal quadratic
|
|
probing. This method is space-efficient -- there is no pointer overhead --
|
|
and time-efficient for good hash functions.")
