c++ - How to pass a member function as pthread start_routine? -

i got that:

 void* xxx::yyy(void* threadidptr) 

and that:

pthread_create( &tp, null, xxx::yyy, (void*) &i); 

but compile error:

error: argument of type 'void* (xxx::)(void*)' not match  'void* (*)(void*)' 

how pass correctly?

a pointer member function not pointer function. 2 aren't same. trying use pointer member function if pointer function...well, best hope crash , cleanly.

although it's not technically defined behavior, there's @ least reasonable chance can use pointer static member function. can pass pointer object parameter, , can invoke proper member function of object.

other that, can use normal function pthreads expects, , done it.
