class TempFile

Declaration

class TempFile { /* full declaration omitted */ };

Description

Represents a temporary file. The temporary file must be eventually discarded or given a final name and kept. The destructor doesn't implicitly discard because there is no way to properly handle errors in a destructor.

Methods

¶TempFile(llvm::StringRef Name, int FD)

Declared at: llvm/include/llvm/Support/FileSystem.h:852

Parameters
