Description:
HTML Wrap
classhdf-rm-section

H5R_GET_ATTR_NAME retrieves the attribute name for the attribute reference pointed to by ref_ptr. Up to size characters of the name are returned in name; additional characters, if any, are not returned to the user application. If the length of the name, which determines the required value of size, is unknown, a preliminary H5R_GET_ATTR_NAME call can be made. The return value of this call will be the size of the attribute name. That value can then be assigned to size for a second H5R_GET_ATTR_NAME call, which will retrieve the actual name.
