H5Tset_size
(
hid_t dtype_id
,
size_tsize
)
H5Tset_size
sets the total size in bytes,
size
, for a datatype. If the datatype is atomic and size
is decreased so that the significant bits of the datatype extend beyond
the edge of the new size, then the `offset' property is decreased
toward zero. If the `offset' becomes zero and the significant
bits of the datatype still hang over the edge of the new size, then
the number of significant bits is decreased.
The size set for a string should include space for the null-terminator
character, otherwise it will not be stored on (or retrieved from) disk.
Adjusting the size of a string automatically sets the precision
to 8*size
. A compound datatype may increase or decrease
in size as long as its member field is not trailed. All datatypes
must have a positive size.
hid_t dtype_id |
Identifier of datatype to change size. |
size_t size |
Size in bytes to modify datatype. |
