Parameters:
hid_t loc_idIN: Location of object to which attribute is attached
const char *obj_nameIN: Name of object to which attribute is attached, relative to location
const char *attr_name    IN: Attribute name
H5A_info_t *ainfoOUT: Struct containing returned attribute information
hid_t lapl_idIN: Link access property list

Description:

H5Aget_info_by_name retrieves information for an attribute, attr_name, that is attached to an object, specified by its location and name, loc_id and obj_name, respectively. The attribute information is returned in the ainfo struct.

If loc_id fully specifies the object to which the attribute is attached, obj_name should be '.' (a dot).

The ainfo struct is described in H5Aget_info.

The link access property list, lapl_id, may provide information regarding the properties of links required to access the object, obj_name. See “Link Access Properties” in the H5P APIs.

Returns:

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