Follow these simple rules and stay out of trouble:
|
|
|
|
\li \Bold{Handle discipline:} The HDF5 API is rife with handles or
|
|
identifiers, which you typically obtain by creating new HDF5 items, copying
|
|
items, or retrieving facets of items. Consequently, \Bold{and most importantly}, you are
|
|
responsible for releasing the underlying
|
|
resources via the matching \TText{H5*close()} call, or deal with the consequences
|
|
of resource leakage.
|
|
\li \Bold{Closed means closed:} Do not pass identifiers that were previously
|
|
\TText{H5*close()}-d to other API functions! It will generate an error.
|
|
\li \Bold{Dynamic memory allocation:} The API contains a few functions in which the
|
|
HDF5 library dynamically allocates memory on the caller's behalf. The caller owns
|
|
this memory and eventually must free it by calling H5free_memory() and not language-explicit memory functions.
|
|
\li \Bold{Don't modify while iterating:} Do not modify the underlying collection when an
|
|
iteration is in progress!
|
|
\li \Bold{Use of locations:} Certain API functions, typically called \TText{H5***_by_name}
|
|
use a combination of identifiers and path names to refer to HDF5 objects.
|
|
If the identifier fully specifies the object in question, pass \TText{'.'} (a dot)
|
|
for the name!
