* H5FD_FEAT_DEFAULT_VFD_COMPATIBLE VFD feature flag (HDFFV-10214) * H5FDdriver_query() API call (HDFFV-10215) * Fix to skip SWMR tests that when the current VFD is not compatible with the default VFD (HDFFV-10197) * Removed obsolete compiler versions from config/gnu-flags (HDFFV-9937) * Many warning fixes

|
||
*
|
||
* This program is intended to run concurrently with the
|
||
* swmr_remove_reader program. It is also run AFTER a sequential
|
||
* (not concurrent!) invoking of swmr_writer so the writer
|
||
* can dump a bunch of data into the datasets. Otherwise,
|
||
* there wouldn't be much to shrink :)
