Extract the elementtype type for a parameter. Note that elementtype() can only be applied to call arguments, not function declaration parameters.
Synopsis
Declared in <llvm/IR/InstrTypes.h>
Type*
getParamElementType(unsigned int ArgNo) const;Return Value
The instances of the Type class are immutable: once they are created, they are never changed. Also note that only one instance of a particular type is ever created. Thus seeing if two types are equal is a matter of doing a trivial pointer comparison. To enforce that no two equal instances are created, Type instances can only be created via static factory methods in class Type and in derived classes. Once allocated, Types are never free'd.
