+<tag/Declaration/<tt/size_t __fastcall__ strxfrm (char* s1, const char* s2, size_t n);/
+<tag/Description/The <tt/strxfrm/ function transforms the string pointed to by
+s2 and places the resulting string into the string pointed to by s1. The
+transformation is such that if the <tt/strcmp/ function is applied to two
+transformed strings, it returns a value greater than, equal to, or less than
+zero, corresponding to the result of the <tt/strcoll/ function applied to the
+same two original strings. No more than n characters are placed into the
+resulting array pointed to by s1, including the terminating null character.
+<tag/Limits/<itemize>
+<item><tt/s1/ and <tt/s2/ must not point to the same memory area, otherwise
+the behaviour is undefined.
+<item>If <tt/n/ is zero, <tt/s1/ may be a NULL pointer.
+<item>The function is only available as fastcall function, so it may only
+be used in presence of a prototype.
+<item>Since cc65 doesn't support different charcter sets, <tt/strxfrm/ will
+just copy s2 to s1 using <tt><ref id="strncpy" name="strncpy"></tt>.
