In a lot of programs my gensortutility turned out to be very useful. It consists simply of the header file “gensort.h“, contained in the above package. To obtain a sorting routine, simply define the name of the routine, the data type you want to sort and how to compare items with preprocessor symbols, and then simply say

There you have a fast and reliable Quicksort (or alternatively Heapsort) routine! The abilities of the gensort generated routines are identical to those obtained by using the qsort routine from the ANSI-C standard, but by far faster! The package contains a test program testsort.c that compares the qsort routines versus the gensortgenerated ones.

A long description how to use it along with some easy examples is at the begin of the header file gensort.h itself.
