This does work. The size is 9. typedef struct HeaderTag { ULONG HeaderLength; CHAR PackingType; USHORT NumRows; USHORT PackedSize; } __attribute__ ((packed)) HeaderType, *pHeaderType; Tom Stokes If anyone is interested, this is from manpages: ---------------------------------------------------------------------------- ---------------------------------------- packed The packed attribute specifies that a variable or structure field should have the smallest possible alignment--one byte for a variable, and one bit for a field, unless you specify a larger value with the aligned attribute. Here is a structure in which the field x is packed, so that it immediately follows a: struct foo { char a; int x[2] __attribute__ ((packed)); }; - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
