Question

I’m trying to populate a vector threads; with a function that iterates through a directory, but im running into problems

this is what I have:

//create vector of threads
vector<thread> threads;

for(unsigned i=0; i < threadNum; ++i)
{
    threads.push_back(thread(grep(arguments, r))); //best c++ 11
}

and this is the error that I am getting:

error c2440: '<function-style-cast>': cannot conver from 'void' to std::thread

can anyone explain why and perhaps hint an answer? thank you

edit

grep is the function name

void grep(Arguments arguments, regex r){}

Answer 1

Presumably you mean to say something like

threads.push_back(thread(grep, arguments, r));

or even better:

threads.emplace_back(grep, arguments, r);
