NAME

6       strxfrm - string transformation
7

SYNOPSIS

9       #include <string.h>
10
11       size_t strxfrm(char *dest, const char *src, size_t n);
12

DESCRIPTION

14       The  strxfrm() function transforms the src string into a form such that
15       the result of strcmp(3) on two strings that have been transformed  with
16       strxfrm()  is  the  same as the result of strcoll(3) on the two strings
17       before their transformation.  The first  n  bytes  of  the  transformed
18       string  are  placed  in  dest.  The transformation is based on the pro‐
19       gram's current locale for category LC_COLLATE.  (See setlocale(3)).
20

RETURN VALUE

22       The strxfrm() function returns the number of bytes  required  to  store
23       the  transformed  string  in  dest  excluding the terminating null byte
24       ('\0').  If the value returned is n or more, the contents of  dest  are
25       indeterminate.
