Name: H5Tset_size
Signature:
herr_t H5Tset_size( hid_t dtype_id, size_tsize )
Purpose:
Sets the total size for an atomic datatype.
Description:
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.
Parameters:
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
