    about: little demo howto use stringstreams

    stringstreams allow to work on strings the same way one work
    on files.
    for example one could open a stringstream and write to it -> 
    the stringstream itself allocates enough memory to hold all the
    data.  

    PROBLEM: work only with glibc (not win32 api)

#include <stdio.h>

int main()
{
  char*   bp;
  size_t  size;
  FILE*   stream;

  /* get handle */
  stream= open_memstream(&bp, &size);

  /* write into the stream, no need to alloc memory for bp */
  fprintf(stream, "hello");
  fflush(stream);
  printf("buf = `%s', size = %d\n", bp, size);
  fprintf(stream, ", world");
  fclose(stream);
  printf("buf = `%s', size = %d\n", bp, size);

  return 0;
