strxfrm(3)


NAME

   strxfrm - string transformation

SYNOPSIS

   #include <string.h>

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

DESCRIPTION

   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

   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.
