NAME

6       strxfrm - string transformation
7

SYNOPSIS

9       #include <string.h>
10
11       size_t strxfrm(char *restrict dest, const char *restrict src,
12                      size_t n);
13

DESCRIPTION

15       The  strxfrm() function transforms the src string into a form such that
16       the result of strcmp(3) on two strings that have been transformed  with
17       strxfrm()  is  the  same as the result of strcoll(3) on the two strings
18       before their transformation.  The first  n  bytes  of  the  transformed
19       string  are  placed  in  dest.  The transformation is based on the pro‐
20       gram's current locale for category LC_COLLATE.  (See setlocale(3)).
21

RETURN VALUE

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