Name: H5Aread
Signature:
herr_t H5Aread(hid_t attr_id, hid_t mem_type_id, void *buf )
Purpose:
Reads an attribute.
Description:
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.

Parameters:
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
