H5open
(void)
H5open
initialize the library. This function is
normally called automatically, but if you find that an
HDF5 library function is failing inexplicably, try calling
this function first.
H5close
(void)
H5close
flushes all data to disk,
closes all file identifiers, and cleans up all memory used by
the library. This function is generall called when the
application calls exit
, but may be called earlier
in event of an emergency shutdown or out of desire to free all
resources used by the HDF5 library.
H5dont_atexit
(void)
atexit
cleanup routine.
H5dont_atexit
indicates to the library that an
atexit()
cleanup routine should not be installed.
The major purpose for this is in situations where the
library is dynamically linked into an application and is
un-linked from the application before exit()
gets
called. In those situations, a routine installed with
atexit()
would jump to a routine which was
no longer in memory, causing errors.
In order to be effective, this routine must be called before any other HDF function calls, and must be called each time the library is loaded/linked into the application (the first time and after it's been un-loaded).
H5get_libversion
(unsigned *majnum
,
unsigned *minnum
,
unsigned *relnum
)
H5get_libversion
retrieves the major, minor, and release
numbers of the version of the HDF library which is linked to
the application.
majnum
minnum
relnum
H5check_version
(unsigned majnum
,
unsigned minnum
,
unsigned relnum
)
H5check_version
verifies that the arguments match the
version numbers compiled into the library. This function is intended
to be called from user to verify that the versions of header files
compiled into the application match the version of the HDF5 library.
Due to the risks of data corruption or segmentation faults,
H5check_version
causes the application to abort if the
version numbers do not match.
