astCopy
-
Copy an Object
- Description:
- This function creates a copy of an Object and returns a pointer
to the resulting new Object. It makes a "deep" copy, which
contains no references to any other Object (i.e. if the original
Object contains references to other Objects, then the actual
data are copied, not simply the references). This means that
modifications may safely be made to the copy without indirectly
affecting any other Object.

- AstObject
astCopy( const AstObject
this )

this

Pointer to the new Object.
- Notes:
- A null Object pointer (AST__NULL) will be returned if this
function is invoked with the AST error status set, or if it
should fail for any reason.
