Ovanes,

I would like to start multiple preprocessing threads. Is wave thread-safe or there some points I should take in account?

Wave object instances are not thread safe. Wave doesn't contain any thread related code at all. You'll have to protect the wave object instances from thread related issues yourself.

Being thread-unaware does not mean your code is thread unsafe: you're most likely providing the basic thread-safety guarantee as defined in

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2298.html

as long as boost::wave::context etc. do not have class static data.

Yes, that is exactly what I mean: reentrant member functions and no static data which can be damaged by parallel execution of multiple context instances... My intention is: I have a lot of source files, which I would like to preprocess by some number of threads. Each thread will own a dedicated context instance and preprocess the source file. Will this work, of do you for example have some static tables or whatever, which would be written by this contexts at the same time? With Kind Regards, Ovanes Markarian
