hashtable implementation in C?

I was wondering if you knew of a robust implement开发者_如何学编程ation of a hashtable in C. I'm looking for something other than ghashtable in glib. Thanks.

I've heard good things about the GLib Hash Table.

In C:

• As previously mentioned g_hash_table in gLib: http://library.gnome.org/devel/glib/stable/glib-Hash-Tables.html
• uthash: https://github.com/troydhanson/uthash
• khash in klib: https://github.com/attractivechaos/klib
• cdada_map in libcdada: https://github.com/msune/libcdada (C API, backend C++)

If you can/want to use C++:

• std::map in libstdc++ (look into std::unordered_map too)
• As noted before (updated link) sparsehash: https://github.com/sparsehash/sparsehash (look into dense too)

Will this hashtable work? (got the link from the second post of this thread)

Perhaps this one will?

(got the above from a Google search for "hashtable in c", am not a C programmer)

For a hash table I'd use google-sparsehash

PD: I don't know your requirements, but take a look at HDF5, bear in mind it exists just in case.

update

Memory Structures Library (MemSL2), o MemSL2 in another link it has implementations (one in pure C and wrappers for C++) of structures, for example, AVL trees, threaded trees, ..., and

• Hash Tables with Separate Chaining,
• Hash Tables with User-Defined Paging
• Hash Tables with Dynamic Paging

A simple one in libc, see <hsearch.h> and man hsearch.

Update: just found that you can implement hashtable very easily with the help of hlist from Linux kernel. Take a look at <list.h> in Linux kernel source code for hlist_head/node and their operations.

You might want to look into using the Apache Portable Runtime? It's license is very liberal and it provides a decent hashtable implementation:
