 *
 *      If DRIVER is non-NULL, then it will try to open the file with that
 *      driver first. We assume that the user knows what they are doing so, if
 *      we fail, then we won't try other file drivers.
 * Return:
 *      On success, returns a file id for the opened file. If DRIVERNAME is
 *      non-null then the first DRIVERNAME_SIZE-1 characters of the driver
 *      name are copied into the DRIVERNAME array and null terminated.
 *
 *      Otherwise, the function returns FAIL. If DRIVERNAME is non-null then

 * Programmer:
 *      Lost in the mists of time.
 * Modifications:
 *      Robb Matzke, 2000-06-23
 *      We only have to initialize driver[] on the first call, thereby
 *      preventing memory leaks from repeated calls to H5Pcreate().
 *
 *      Robb Matzke, 2000-06-23
 *      Added DRIVERNAME_SIZE arg to prevent overflows when writing to
 *      DRIVERNAME.
 *
 *      Robb Matzke, 2000-06-23
 *      Added test to prevent coredump when the file could not be opened by
 *      any driver.
 *
 *      Robb Matzke, 2000-06-23
 *      Changed name from H5ToolsFopen() so it jives better with the names we
 *      already have at the top of this source file.
 *
 *      Thomas Radke, 2000-09-12
 *      Added Stream VFD to the driver[] array.
 *
 *      Bill Wendling, 2001-01-10
 *      Changed macro behavior so that if we have a version other than 1.2.x
 *      (i.e., > 1.2), then we do the drivers check.
 *
 *      Bill Wendling, 2001-07-30
 *      Added DRIVER parameter so that the user can specify "try this driver"
 *      instead of the default behaviour. If it fails to open the file with
 *      that driver, this will fail completely (i.e., we won't try the other
 *      drivers). We're assuming the user knows what they're doing. How UNIX
 *      of us.

 *
 * Algorithm
 *
 * In a inner loop, the parameters from SSET are translated into temporary
 * variables so that 1 row is printed at a time (getting the coordinate indices
 * at each row).
 * We define the stride, count and block to be 1 in the row dimension to achieve
 * this and advance until all points are printed.
 * An outer loop for cases where dimensionality is greater than 2D is made.
 * In each iteration, the 2D block is displayed in the inner loop. The remaining
 * slower dimensions above the first 2 are incremented one at a time in the outer loop
 *
 * The element position is obtained from the matrix according to:

 * Audience:    Public

 * Purpose: Print some values from a dataset with a simple data space.
 * Description:
 *      This is a special case of h5tools_dump_dset(). This function only
 *      intended for dumping datasets -- it does strip mining and some other
 *      things which are unnecessary for smaller objects such as attributes
 *      (to print small objects like attributes simply read the attribute and
 *      call h5tools_dump_simple_mem()).
 * Return:
 *      On success, the function returns SUCCEED. Otherwise, the function
 *      returns FAIL.
