Hi,
   I've got a stuct like 

typedef struct {
   short id;
   char  fc[3];
   short pos;
   ...
} trREC,*tpREC;

when I go to read the struct from a binary file the struct
appears to have padded a space between then end of fc and
start of pos. Is there a pragma to make sure the struct uses
the minimum amout of space? How much of a speed penalty will
I pay in the rest of the code (hav'ing non-word boundries)?
Would it be better skip the pragma and just to read the
fields one at a time?

Thanks
   Eric
