NAME         top

       strxfrm - string transformation

SYNOPSIS         top

       #include <string.h>

       size_t strxfrm(char *restrict dest, const char *restrict src,
                      size_t n);

DESCRIPTION         top

       The strxfrm() function transforms the src string into a form such
       that the result of strcmp(3) on two strings that have been
       transformed with strxfrm() is the same as the result of
       strcoll(3) on the two strings before their transformation.  The
       first n bytes of the transformed string are placed in dest.  The
       transformation is based on the program's current locale for
       category LC_COLLATE.  (See setlocale(3)).

RETURN VALUE         top

       The strxfrm() function returns the number of bytes required to
       store the transformed string in dest excluding the terminating
       null byte ('\0').  If the value returned is n or more, the
       contents of dest are indeterminate.
