		integer, intent(in)	minnum,
		integer, intent(in)	relnum,
		integer, intent(out)	error
	)

Verifies that library versions are consistent.

Parameters

majnum	Major version of the library.
minnum	Minor version of the library.
relnum	Release version of the library.
error	Returns 0 if successful and -1 if it fails.

h5close_f()

subroutine, public h5lib::h5close_f

(

integer, intent(out)

error

)

Closes HDF5 Fortran interface.

Parameters

error

Returns 0 if successful and -1 if it fails.

h5dont_atexit_f()

subroutine, public h5lib::h5dont_atexit_f

(

integer, intent(out)

error

)

Instructs library not to install atexit cleanup routine.

Parameters

error

Returns 0 if successful and -1 if it fails.

h5garbage_collect_f()

subroutine, public h5lib::h5garbage_collect_f

(

integer, intent(out)

error

)

Garbage collects on all free-lists of all types.

Parameters

error

Returns 0 if successful and -1 if it fails.

h5get_libversion_f()

subroutine, public h5lib::h5get_libversion_f	(	integer, intent(out)	majnum,

)

Convert time_t structure (C) to Fortran DATE AND TIME storage format.

Parameters

stdtime_t

Object of type time_t that contains a time value

Returns

datetime A date/time array using Fortran conventions:

• datetime(1) = year
• datetime(2) = month
• datetime(3) = day
• datetime(4) = 0 ! time is expressed as UTC (or GMT timezone)
• datetime(5) = hour
• datetime(6) = minute
• datetime(7) = second
• datetime(8) = millisecond – not available, assigned - HUGE(0)

		type(c_ptr), intent(in), value	end
	)

Computes the offset in memory.

Parameters
