STRANAXFRM(3)                C Programmer's Manual               STRANAXFRM(3)

NAME
       stranaxfrm - make a string into canonical form for anagram comparison

SYNOPSIS
       #include <publib.h>
       char *stranaxfrm(char *str);

DESCRIPTION
       stranaxfrm transforms a string into a canonical form for anagram
       comparisons.  To check whether two strings are anagrams of each other
       (i.e., they contain the same characters, but in different order),
       compare their canonical forms.  The canonical form merely has all the
       characters in the string sorted into ascending order.

       To write a program to find anagrams, first convert a word list into
       canonical order, then look up words in that version of the word list by
       transforming them also to canonical order.

RETURN VALUE
       stranaxfrm returns its argument.

BUGS
       This function is of a whimsical nature.
