The GPERF program creates perfect hash functions. From the author:
|

|
|
While teaching a data structures course at University of California,
|
|
Irvine, I developed a program called GPERF that generates perfect hash
|
|
functions for sets of key words. A perfect hash function is simply:
|
|
|
|
A hash function and a data structure that allows
|
|
recognition of a key word in a set of words using
|
|
exactly 1 probe into the data structure.
|
|
|
|
Output from the GPERF program is used to recognize reserved words in
|
|
the GNU C, GNU C++, and GNU Pascal compilers, as well as with the GNU
|
|
indent program.
