GPERF(1)

NAME
gperf - generate a perfect hash function from a key set

SYNOPSIS
gperf [ -adghijklnoprsStv ] [ keyfile ]

DESCRIPTION
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 generates a pair of C source code routines that perform the hashing and table lookup. All generated code is directed to the standard output. Please refer to the gperf.texinfo file for more information. This file is distributed with gperf release.
