* Chapter: H5Tools Library
* Purpose: Open a file with various VFL drivers.
* Description:
* Loop through the various types of VFL drivers trying to open FNAME.
* If the HDF5 library is version 1.2 or less, then we have only the SEC2
* driver to try out. If the HDF5 library is greater than version 1.2,
* then we have the FAMILY, SPLIT, and MULTI drivers to play with.
*
* 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
* the first byte is set to the null terminator.
* 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.
