STRXFRM(3) Linux Programmer's Manual 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 pro-
     gram'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.
