 *  @brief Provides write access to trace streams, which consist of multiple
 *  buffers.

 */

/** \defgroup wstream Stream Writer Interface
 *
 * This interface provides functions for writing trace at stream level.
 * A stream is part of a trace and consists of up to four buffers
 * (event buffer, definition buffer, snapshots buffer, statistics buffer).
 * 
 * wstream is structured similarly to writer.
 *
 * Use this interface, if you want to a specific stream and the writer
 * interface does not provide the desired access.
 *
 * \section wstream_example A short Example
 *
 *  \code
 *  #include <assert.h>
 *  #include "otf.h"
 *
 *  int main( int argc, char** argv ) {
 *  \endcode
 *
 *      Declare a file manager and a writer.
 *      \code
 * 	    OTF_FileManager* manager;
 * 	    OTF_WStream* wstream;
 * 	    \endcode
 *
 *     	Initialize the file manager. Open at most 100 OS files.
 *     	\code
 *     	manager= OTF_FileManager_open( 100 );
 * 	    assert( manager );
 * 	    \endcode
 *
 * 	    Initialize the wstream object. Open file "test", writing the first stream.
 * 	    \code
 * 	    wstream = OTF_WStream_open( "test", 0, manager );
 *      assert( wstream );
 *      \endcode
 *      
 *      Write some definition records.
 *      \code
 *      OTF_WStream_writeDefTimerResolution( wstream, 1000 );
 *      OTF_WStream_writeDefProcess( wstream, 1, "proc one", 0 );
 *      \endcode
 *
 *      Clean up before exiting the program.
 *      \code
 *      OTF_WStream_close( wstream );
 *      OTF_FileManager_close( manager );
 *
 *		return 0;
 * }
 * \endcode
 *
 * Compile this using $ gcc -o test test.c `otfconfig --libs`.
 *
 * When executing this program it only writes one file (test.0.def),
 * containg the written records.
 *
