Detailed Description

This module defines functions that allow you to inspect the uses of a LLVMValueRef.

It is possible to obtain an LLVMUseRef for any LLVMValueRef instance. Each LLVMUseRef (which corresponds to a llvm::Use instance) holds a llvm::User and llvm::Value.


Function Documentation

Obtain the first use of a value.

Uses are obtained in an iterator fashion. First, call this function to obtain a reference to the first use. Then, call LLVMGetNextUse() on that instance and all subsequently obtained instances until LLVMGetNextUse() returns NULL.

Obtain the next use of a value.

This effectively advances the iterator. It returns NULL if you are on the final use and no more are available.

References llvm::unwrap(), and llvm::wrap().

Obtain the value this use corresponds to.

Obtain the user value for a user.

The returned value corresponds to a llvm::User type.
