From a1bdcedc3879510a874d24c450e07feb170d9cd6 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Wed, 15 Jul 2009 17:29:42 +0000 Subject: Add a Force option to raw_fd_ostream to specify whether opening an existing file is considered an error. Convert several tools to use raw_fd_ostream instead of std::ostream, and to use this new option instead of doing a manual check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75801 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/raw_ostream.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'lib/Support/raw_ostream.cpp') diff --git a/lib/Support/raw_ostream.cpp b/lib/Support/raw_ostream.cpp index 0595fe4..b13d922 100644 --- a/lib/Support/raw_ostream.cpp +++ b/lib/Support/raw_ostream.cpp @@ -246,7 +246,7 @@ void format_object_base::home() { /// occurs, information about the error is put into ErrorInfo, and the /// stream should be immediately destroyed; the string will be empty /// if no error occurred. -raw_fd_ostream::raw_fd_ostream(const char *Filename, bool Binary, +raw_fd_ostream::raw_fd_ostream(const char *Filename, bool Binary, bool Force, std::string &ErrorInfo) : pos(0) { ErrorInfo.clear(); @@ -266,6 +266,8 @@ raw_fd_ostream::raw_fd_ostream(const char *Filename, bool Binary, if (Binary) Flags |= O_BINARY; #endif + if (!Force) + Flags |= O_EXCL; FD = open(Filename, Flags, 0664); if (FD < 0) { ErrorInfo = "Error opening output file '" + std::string(Filename) + "'"; -- cgit v1.1
