.SH DESCRIPTION
|
|
|
|
\fIgperf\fP reads a set of ``keys'' from \fIkeyfile\fP (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 \fIC\fP source code routines that perform the
|
|
hashing and table lookup. All generated code is directed to the
|
|
standard output.
|
|
|
|
Please refer to the \fIgperf.texi\fP file for more information.
