Constructor & Destructor Documentation

EMF::DATASTREAM::DATASTREAM(::FILE*fp=0)[inline]
       Constructor for DATASTREAM.

       Parametersfp optional file pointer (but must be assigned before any output occurs.)

Detailed Description

       Support different endian modes when reading and writing the metafile.

       To support different endian modes, rather than just writing the structures directly to a file via fwrite(
       &emr, ...), we have to write each element of the structure separately, swapping bytes as necessary.
       datastream supports this. Remarkably similar to the QDataStream class from Qt. So, too, for reading.
