H5Pset_fapl_split
is a compatibility function that
enables the multi-file driver to emulate the split driver from
HDF5 Releases 1.0 and 1.2.
The split file driver stored metadata and raw data in separate files
but provided no mechanism for separating types of metadata.
fapl_id
is a file access property list identifier.
meta_ext
is the filename extension for the metadata file.
The extension is appended to the name passed to H5FDopen
,
usually from H5Fcreate
or H5Fopen
,
to form the name of the metadata file.
If the string %s is used in the extension, it works like the
name generator as in H5Pset_fapl_multi
.
meta_plist_id
is the file access property list identifier
for the metadata file.
raw_ext
is the filename extension for the raw data file.
The extension is appended to the name passed to H5FDopen
,
usually from H5Fcreate
or H5Fopen
,
to form the name of the rawdata file.
If the string %s is used in the extension, it works like the
name generator as in H5Pset_fapl_multi
.
raw_plist_id
is the file access property list identifier
for the raw data file.
If a user wishes to check to see whether this driver is in use,
the user must call H5Pget_driver
and compare the
returned value to the string H5FD_MULTI
.
A positive match will confirm that the multi driver is in use;
HDF5 provides no mechanism to determine whether it was called
as the special case invoked by H5Pset_fapl_split
.
