HDF5 Glossary

(Under construction! This is the bare beginning of a Glossary to accompany the HDF5 documentation; it is by no means complete.)

Basic Types
Complex Types
Disk I/O Types

Since many of the typedefs in the HDF5 API are not well-defined yet, the types below may change radically en route to a final API...

char - 8-bit character (only for ASCII information)
int8 - 8-bit signed integer
uint8 - 8-bit unsigned integer
int16 - 16-bit signed integer
uint16 - 16-bit unsigned integer
int32 - 32-bit signed integer
uint32 - 32-bit unsigned integer
intn - "native" signed integer
uintn - "native" unsigned integer
int64 - 64-bit signed integer (new)
uint64 - 64-bit unsigned integer (new)
float32 - 32-bit IEEE float
float64 - 64-bit IEEE float

hid_t - 32-bit unsigned integer used as ID for memory objects
hoid_t - 32-bit unsigned integer (currently) used as ID for disk-based objects
hbool_t - boolean to indicate true/false/error codes from functions
herr_t - 32-bit integer to indicate succeed/fail codes from functions

Disk I/O Types:

hoff_t - (64-bit?) offset on disk in bytes
hlen_t - (64-bit?) length on disk in bytes
