This method isnt what i am looking for....I know how
to see the individual bits in a byte but i want to be
able to say read the next n bits and see if they are 
on or off....maybe i want the next 7 or the next 22
bits....I found some code in the snippits archive
that seems promising for this purpose but i am still
trying to figure out how to implement it....

Its got functions like these: 

bfile * bfopen(char *name, char *mode);
int     bfread(bfile *bf);
void    bfwrite(int bit, bfile *bf);
void    bfclose(bfile *bf);

and a struct like this:

typedef struct  {
      FILE *  file;       /* for stream I/O   */
      char    rbuf;       /* read bit buffer  */
      char    rcnt;       /* read bit count   */
      char    wbuf;       /* write bit buffer */
      char    wcnt;       /* write bit count  */
} bfile;

I am trying to figure out how to chop out the junk
and use this,but if some one esle had some thing better
i would welcome the help.

Thnaks.
