c++ - force exit from readline() function

Question

I am writing program in c++ which runs GNU readline in separate thread. When main thread is exited I need to finish the thread in which readline() function is called. The readline() function is returned only when standart input came (enter pressed). Is there any way to send input to application or explicitly return from readline function? Thanks in advance.

Answer 1

Instead of returning from main thread, call exit(errno). All other threads will be killed nastily!

Or, if you wanted to be nicer, and depending on your OS, you could send a signal to the readline thread, which would interrupt the syscall.

Or, if you wanted to be cleverer, you could run readline in async mode, using a select() loop with a timeout so that your thread never blocks in readine functions, and your thread can clean up after itself.
