strxfrm(3C)         (C Programming Language Utilities)          strxfrm(3C)


   NAME
         strxfrm - string transformation

   SYNOPSIS
         #include <string.h>

         sizet strxfrm (char *s1, const char *s2, sizet n);

   DESCRIPTION
         strxfrm transforms the string s2 and places the resulting string into
         the array s1.  The transformation is such that if strcmp is applied
         to two transformed strings, it will return the same result as strcoll
         applied to the same two original strings.  The transformation is
         based on the program's locale for category LCCOLLATE [see
         setlocale(3C)].

         No more than n characters will be placed into the resulting array
         pointed to by s1, including the terminating null character. If n is
         0, then s1 is permitted to be a null pointer. If copying takes place
         between objects that overlap, the behavior is undefined.

         strxfrm returns the length of the transformed string (not including
         the terminating null character).  If the value returned is n or more,
         the contents of the array s1 are indeterminate.

   EXAMPLE
         The value of the following expression is the size of the array needed
         to hold the transformation of the string pointed to by s.

               1 + strxfrm(NULL, s, 0);

   DIAGNOSTICS
         On failure, strxfrm returns (sizet) -1.
