Read it into an array of (unsigned) char, do any formatting / alignment checks that you can, and then extract the data into the variables you want it in. If there are raw binary values of more than one byte, extract them explicitly: MyWordVal = buf[2] + ( buf[3] * 256 ); /* data stream is little endian */ This is portable and clear to any future maintainer. The efficiency loss is negligible. Cheers, Rob _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
