NAMEace_gperf - generate a perfect hash function from a key set
SYNOPSISace_gperf [ -adghijklnoprsStv ] [ keyfile ]
DESCRIPTIONace_gperf reads a set of ``keys'' from keyfile (or, by default, from the standard input) and attempts to find a non-minimal perfect hashing function that recognizes a member of the key set in constant, i.e., O(1), time. If such a function is found the program gener‐ ates a pair of C source code routines that perform the hashing and table lookup. All gen‐ erated code is directed to the standard output. Please refer to the ace_gperf.texinfo file for more information. This file is distributed with ace_gperf release.
