H5Aread
(hid_t attr_id
,
hid_t mem_type_id
,
void *buf
)
H5Aread
reads an attribute, specified with
attr_id
. The attribute's memory datatype
is specified with mem_type_id
. The entire
attribute is read into buf
from the file.
Datatype conversion takes place at the time of a read or write and is automatic. See the Data Conversion section of The Data Type Interface (H5T) in the HDF5 User's Guide for a discussion of data conversion, including the range of conversions currently supported by the HDF5 libraries.
hid_t attr_id |
IN: Identifier of an attribute to read. |
