C hash table library linux

Sep 20,  · If you mean a kernel module (an actual “Linux module”), then look at source/hashtable.c If you're prepared to switch to C++ then you can use the std::hashmap and std::hashtable templates (which have the advantage of compile-time type checking). Any C structure can be stored in a hash table using uthash. Just add a UT_hash_handle to the structure and choose one or more fields in your structure to act as the key. Then use these macros to store, retrieve or delete items from the hash table. On success, hsearch() returns a pointer to an entry in the hash table. hsearch() returns NULL on error, that is, if action is ENTER and the hash table is full, or action is FIND and item cannot be found in the hash table.

Judy is a C library that implements a sparse dynamic array. Judy arrays are declared simply with a null pointer and consume memory only when populated. They can grow to use all available memory if desired. Judy's key benefits are scalability, high performance, and memory efficiency. It can be used for dynamically sized arrays, associative arrays or a simple-to-use interface that requires no. Why are there no hashtables in the C standard library? Ask Question People use C these days to implement things like Python, Ruby, Apache, or the Linux kernel. These are projects that use all of their own data structures anyway, and they wouldn't be likely to use something like the STL. UTHash is a hash table library. Mar 27,  · Hashing Library for C tagged C, c reference manual, Fedora, Hash, Library, Linux, Programming, Tip. Hashing Library for C tagged C, c reference manual, Fedora, Hash, Library, Linux, Programming, Tip. libghthash is a Generic Hash Table which is meant to be easy to extend, portable, clear in its code and easy to use. The mhash library provides an easy to use C interface for several hash algorithms (also known as "one-way" algorithms). These can be used to create checksums, message digests and more. Currently, MD5, SHA1, GOST, TIGER, RIPE-MD, HAVAL and several other algorithms are pc-supply.biz support HMAC generation (a mechanism for message authentication using cryptographic hash functions, and . Sep 20,  · If you mean a kernel module (an actual “Linux module”), then look at source/hashtable.c If you're prepared to switch to C++ then you can use the std::hashmap and std::hashtable templates (which have the advantage of compile-time type checking).Definitely look into the Linux kernel data structures. The standard library does come with a half-baked hash table implementation[1]. Any C structure can be stored in a hash table using uthash. Just add a UT_hash_handle to the structure and choose one or more fields in your structure to act as. Off the shelf, use the ones you can from hsearch(3): hash table management Some are posix standard, and some are gnu extensions A hash. UTHash, Judy Arrays, and SunriseDD (Sunrise Data Dictionary for C) are probably your best bets out of the 10 options considered. The hcreate function creates a hashing table which can contain at least nel As an extension the GNU C Library provides an additional set of functions with a. The hsearch() function searches the hash table for an item with the same key as item (where "the same" is determined using strcmp(3)), and if successful returns. What about uthash - a hash table for C structures. Supports both strings, and integer tuples. uthash has no restriction vs. keys: key and structure can have any . Then what C/C++ hash libraries are available? Only glib hash, CC's hashtable and ghthash implement most of common operations. Mac PeakMem (MB), Linux-intCPU (sec), Linux-strCPU (sec), Linux PeakMem (MB). Hash Table Library for C. Contribute to zfletch/zhash-c development by creating an account on GitHub. Tested on Arch Linux with GCC Check out our list of hash libraries for C programmers and those who D. Hanson, any C structure can be stored in a hash table using uthash.
