H5Iregister
(
H5I_type_t type
,
void *object
)
H5Iregister
allocates space for a new ID
and returns an identifier for it.
The type
parameter is the identifier for
the ID type to which this new ID will belong.
This identifier must have been created by a call to
H5Iregister_type
.
The object
parameter is a pointer to the memory
which the new ID will be a reference to.
This pointer will be stored by the library and
returned to you via a call to H5Iobject_verify
.
If a C routine that takes a function pointer as an argument is called from within C++ code, the C routine should be returned from normally.
Examples of this kind of routine include callbacks such as
H5Pset_elink_cb
and H5Pset_type_conv_cb
and functions such as H5Tconvert
and
H5Ewalk2
.
Exiting the routine in its normal fashion allows the HDF5 C Library to clean up its work properly. In other words, if the C++ application jumps out of the routine back to the C++ “catch” statement, the library is not given the opportunity to close any temporary data structures that were set up when the routine was called. The C++ application should save some state as the routine is started so that any problem that occurs might be diagnosed.
