H5Tset_order(
hid_t dtype_id,
H5T_order_t order
)
H5Tset_order sets the byte order of a datatype.
Byte order can currently be set to any of the following:
H5T_ORDER_LE (0)
H5T_ORDER_BE (1)
H5T_ORDER_VAX (2)
H5T_ORDER_MIXED (3) is a valid value
for order only when returned by the function
H5Tget_order;
it cannot be set with H5Tset_order.
H5T_ORDER_NONE (4) is a valid value
for order, but it has no effect.
It is valid only for fixed-length strings and object and region references
and specifies “no particular order.”
The byte order of a derived datatype is initially the same as that
of the parent type, but can be changed with H5Tset_order.
This function cannot be used with a datatype after it has been committed.
Special considerations:
ENUM datatypes: Byte order must be set before any member
on an ENUM is defined.
Compound datatypes: Byte order is set individually on each member of a compound datatype; members of a compound datatype need not have the same byte order.
Opaque datatypes: Byte order can be set but has no effect.
