[NOTE! LOW=HIGH=H5F_FORMAT_EARLIEST is not * implemented as of version 1.8.0 and setting LOW and HIGH to * H5F_FORMAT_EARLIEST will produce an error currently]. * * Currently, the only two valid combinations for this routine are: * LOW = H5F_FORMAT_EARLIEST and HIGH = H5F_FORMAT_LATEST (the default * setting, which creates objects with the ealiest version possible for * each object, but no upper limit on the version allowed to be created if * a newer version of an object's format is required to support a feature * requested with an HDF5 library API routine), and LOW = H5F_FORMAT_LATEST * and HIGH = H5F_FORMAT_LATEST (which is described above). * * The LOW and HIGH values set with this routine at imposed with each * HDF5 library API call that creates objects in the file. API calls that * would violate the LOW or HIGH format bound will fail. * * Setting the LOW and HIGH values will not affect reading/writing existing * objects, only the creation of new objects. * * Note: Eventually we want to add more values to the H5F_libver_t * enumerated type that indicate library release values where the file * format was changed (like "H5F_FORMAT_1_2_0" for the file format changes * in the 1.2.x release branch and possily even "H5F_FORMAT_1_4_2" for * a change mid-way through the 1.4.x release branch, etc). * * Adding more values will allow applications to make settings like the * following: * LOW = H5F_FORMAT_EARLIEST, HIGH = H5F_FORMAT_1_2_0 => Create objects * with the earliest possible format and don't allow any objects * to be created that require a library version greater than 1.2.x * (This is the "make certain that linked with v1.2.x * of the library can read the file produced" use case) * * LOW = H5F_FORMAT_1_4_2, HIGH = H5F_FORMAT_LATEST => create objects * with at least the version of their format that the 1.4.2 library * uses and allow any later version of the object's format * necessary to represent features used. * (This is the "make certain to take advantage of * in the file format" use case (maybe is smaller * or scales better than an ealier version, which would otherwise * be used)) * * LOW = H5F_FORMAT_1_2_0, HIGH = H5F_FORMAT_1_6_0 => creates objects * with at least the version of their format that the 1.2.x library * uses and don't allow any objects to be created that require a * library version greater than 1.6.x. * (Not certain of a particular use case for these settings, * although its probably just the logical combination of the * previous two; it just falls out as possible/logical (if it turns * out to be hard to implement in some way, we can always disallow * it)) * * Note #2: We talked about whether to include enum values for only library * versions where the format changed and decided it would be less confusing * for application developers if we include enum values for _all_ library * releases and then map down to the previous actual library release which * had a format change. * * Return: Non-negative on success/Negative on failure * * Programmer: Quincey Koziol * Sunday, December 30, 2007 * *------------------------------------------------------------------------- */ herr_t H5Pset_libver_bounds(hid_t plist_id, H5F_libver_t low, H5F_libver_t high) { H5P_genplist_t *plist; /* Property list pointer */ hbool_t latest; /* Whether to use the latest version or not */ herr_t ret_value = SUCCEED; /* return value */ FUNC_ENTER_API(FAIL) H5TRACE3("e", "iFvFv", plist_id, low, high); /* Check args */ /* (Note that this is _really_ restricted right now, we'll want to loosen * this up more as we add features - QAK) */ if(high != H5F_LIBVER_LATEST) HGOTO_ERROR(H5E_ARGS, H5E_BADVALUE, FAIL, "invalid high library version bound") /* Get the plist structure */ if(NULL == (plist = H5P_object_verify(plist_id, H5P_FILE_ACCESS))) HGOTO_ERROR(H5E_ATOM, H5E_BADATOM, FAIL, "can't find object for ID") /* Set values */ latest = (hbool_t)((low == H5F_LIBVER_LATEST) ?
