storing structure(size less than 1 byte) to file

hi,
Plz replay .............for storing a structure(containing a 4 bit length variable) to a file

 

hi,
thanks for your attention, C++ is the language which I forget to mention, can I store the structure (<1 byte) without using type casting. ................hoping your replay

 

You can't have a struct containing less than 1 byte in C or C++.

I'm guessing you declared a bit-field

Code:

struct foo {
  unsigned int bits : 4;
};

This will ALWAYS be padded to some multiple of the size of a char.

Show us some more of what it is you're trying to do.
