NAME
H5Aiterate
PURPOSE
Calls a user's function for each attribute on an object
USAGE
herr_t H5Aiterate (loc_id, attr_num, op, data)
hid_t loc_id; IN: Object (dataset or group) to be iterated over
unsigned *attr_num; IN/OUT: Starting (IN) & Ending (OUT) attribute number
H5A_operator_t op; IN: User's function to pass each attribute to
void *op_data; IN/OUT: User's data to pass through to iterator operator function
RETURNS
Returns a negative value if something is wrong, the return value of the
last operator if it was non-zero, or zero if all attributes were processed.
DESCRIPTION
This function interates over the attributes of dataset or group
specified with 'loc_id'. For each attribute of the object, the
'op_data' and some additional information (specified below) are passed
to the 'op' function. The iteration begins with the '*attr_number'
object in the group and the next attribute to be processed by the operator
is returned in '*attr_number'.
The operation receives the ID for the group or dataset being iterated
over ('loc_id'), the name of the current attribute about the object
('attr_name') and the pointer to the operator data passed in to H5Aiterate
('op_data'). The return values from an operator are:
A. Zero causes the iterator to continue, returning zero when all
attributes have been processed.
B. Positive causes the iterator to immediately return that positive
value, indicating short-circuit success. The iterator can be
restarted at the next attribute.
C. Negative causes the iterator to immediately return that value,
indicating failure. The iterator can be restarted at the next
attribute.
