I'm pondering improved error handling in my LabVIEW interface to HDF5, and I'm wondering if there are any guarantees to be had on HDF5s error codes. I note that the major and minor error codes are simply sequential numbers ored with 0x0C000000.

The question: is there any guaranteed that the symbol -> number mapping (e.g. H5E_CANTALLOC -> 0x0C000nnn) will remain constant from version to version of the toolkit, or even from one person's build to another? As far as I can tell, the answer is "no," but I'm hoping its "yes."
