llvm dev - Nov 2010 - [LLVMdev] Converting raw_ostream to std::ostream

Dear All,

I am currently writing an analysis pass that uses a third-party library.  I want
to write a print() method for my pass  (which takes one of the LLVM raw_ostream
objects) and have it use a method from this third-party library to print out
data.  However, the third-party library uses std::ostream.

Is there a way to create a std::ostream from a raw_ostream?

Hi John T.,

You can't make a std::ostream from a raw_ostream but you can go the other 
direction with it. 
 See http://llvm.org/doxygen/classllvm_1_1raw__os__ostream.html for details 
about raw_os_ostream.

Hope this helps you,

--Sam Crow
