How does one go about doing a memcmp that is aware of the LC_COLLATE setting ? Yes, I know there is strcoll, but the things I am comparing have fixed widths (not null-terminated) and may contain null bytes. It seems that there is no standard C library function to do this.

Copy the strcoll source to another function say "memcoll". 2. Remove the null termination condition from it.   -- AI IP Logged Self discovery comes when a man measures himself against an obstacle - Antoine de Saint Exupery TenaliRaman Uberpuzzler I am no special.
