Detailed Description

A stream which provides both input and output using the same calls.

The data is binary encoded, but architecture independent.

void more::io::syncstream::prolog (  std::ios_base::openmode    mode_ )  [protected]

void more::io::syncstream::set_digits (  int    dig )  [inline]

Use dig mantissa bits precision for writing floats. This defaults to std::numeric_limits<double>::digits. This is an upper limit. When writing a floating point number of type T, the smaller of std::numeric_limits<T>::digits and dig is used.

void more::io::syncstream::set_digits10 (  int    dig10 )

Use dig10 decimal digits precision for writing floats.

void more::io::syncstream::setstate (  std::ios_base::iostate    st )  [inline]

Set the fail state of the stream.

void more::io::syncstream::sync_raw_data (  void *    p, size_t    n )

Sync known size raw data. This breaks the binary dump utility. Be careful if architecture independence is needed.
