WB

https://www.gnu.org/software/wb/
Disk based sorted associative array C library

WB is a disk based, sorted associative array (B-tree) library for SCM. Using WB, large databases can be created and managed from SCM.

Rather than being implemented via hashing, WB uses B-trees, which are optimized for using the minimum number of disk operations. Functions are provided to:

  • create, destroy, open and close disk-files and associative arrays;
  • insert, delete, retrieve, find next, and find previous (with respect to dictionary order of keys);
  • apply functions, delete, or modify values over a range of consecutive key values.

WB is thread safe (so long as HAND structures are not shared between threads). The `put' and `rem' operations allow associations to be used for thread mutexs.
