Function Documentation

mlirLlvmRawFdOStreamCreate()

MlirLlvmRawFdOStream mlirLlvmRawFdOStreamCreate	(	const char *	path,
		bool	binary,
		MlirStringCallback	errorCallback,
		void *	userData )

Create a raw_fd_ostream for the given path.

This wrapper is needed because std::ostream does not provide the file sharing semantics required on Windows.

• path: output file path.
• binary: controls text vs binary mode.
• errorCallback: called with an error message on failure (optional).
• userData: forwarded to errorCallback so it can copy the error message into caller-owned storage (e.g., a std::string). On failure, returns a null stream and invokes the optional error callback with the error message.
