¶void SetOneShotPipeSignalFunction(void (*)()
                                      Handler)

Description

Registers a function to be called in a "one-shot" manner when a pipe signal is delivered to the process (i.e., on a failed write to a pipe). After the pipe signal is handled once, the handler is unregistered. The LLVM signal handling code will not install any handler for the pipe signal unless one is provided with this API (see \ref DefaultOneShotPipeSignalHandler). This handler must be provided before any other LLVM signal handlers are installed: the \ref InitLLVM constructor has a flag that can simplify this setup. Note that the handler is not allowed to call any non-reentrant functions. A null handler pointer disables the current installed function. Note also that the handler may be executed on a different thread on some platforms. This is a no-op on Windows.
