◆ h5zfilter_avail_f()

subroutine h5zfilter_avail_f ( integer, intent(in)  filter,
logical, intent(out)  status,
integer, intent(out)  hdferr 
)

Queries if filter is available.

Parameters

statusFlag; .TRUE. if filter is available, .FALSE. otherwise.
hdferrReturns 0 if successful and -1 if it fails.

See C API: H5Zfilter_avail()

◆ h5zget_filter_info_f()

subroutine h5zget_filter_info_f ( integer, intent(in)  filter,
