Explicitly allocating an LO handle

You can explicitly allocate an LO handle in either of the following ways:

Dynamically, with one of the DataBlade API memory-management functions such as mi_alloc():
```
MI_LO_HANDLE *LO_hdl = mi_alloc(sizeof(MI_LO_HANDLE));
```

On the stack, with a direct declaration:

MI_LO_HANDLE my_LOhndl;
MI_LO_HANDLE *LO_hndl2 = &my_LOhndl;

However, this LO handle is still an opaque C data structure; that is, it is declared as a flat array of undifferentiated bytes and its fields are not available to the DataBlade API module.

Important: The LO handle structure is the only smart-large-object structure that a DataBlade API module can allocate directly. You must allocate other smart-large-object data type structures, such as the LO-specification structure and the LO-status structure, with the appropriate DataBlade API constructor function.
