Detailed Description

This section contains APIs for interacting with LLVMValueRef that correspond to llvm::Constant instances.

These functions will work for any LLVMValueRef in the llvm::Constant class hierarchy.

References llvm::ConstantPointerNull::get(), and llvm::wrap().

◆ LLVMGetUndef()

LLVMValueRef LLVMGetUndef ( LLVMTypeRef  Ty)

Obtain a constant value referring to an undefined value of a type.

See also
