Subject: How to unpack unusual binary structure?

Hello everyone

I try to read binary file and it has section in following format:
(I suspect this comes from .h file)

...
then the bars array (one-byte justification) follows

pragma pack(push,1)
  //---- Standard representation of a quote in the base
  struct RateInfo {
    time_t            ctm;    // current time in seconds
    double            open;
    double            low;
    double            high;
    double            close;
    double            vol;
  };
pragma pack(pop)
...

I don't know what to do with pragma pack. I googled and found that this
is some weird bit-level alignment for records. But I can't figure out,
how do I read and .unpack such records.

Can I just do .read(4 + 5 * 8) and get a record?
How do I decode it if its packed with this pragma pack?

Need help...
