Detailed Description

write FORTRAN binary data ,

This class writes FORTRAN binary data. FORTRAN binary data is always written in chunks of several bytes, where each chunk is preceded and followed by a 4-byte integer byte-count. This class takes care of this structure of byte-counts.

For convenient use we must buffer the output data. The user just pushes data to the stream and calls function end_block() after each data block. We will then write this block with a preceding and following byte-count. This implies the overhead string-streams introduce to this problem. However file I/O is not the part where we emphasize runtime efficiency.

By creating the object the writing process is initialized. Only basic put-functions (for char type) are provided. Use I/O operators for convenient access.
