c - In pthread, how to make a thread wait for a signal -

my objective create thread reusable , not 1 terminates when reaching end of thread function.

this pseudo code of i'm trying achieve pthreads:

bool dorun = true;  void thread_func( void* p ) {     while( dorun ) {         waitforsignal() // waitforsingleobject         // run thread     } } 

i used win32 function waitforsingleobject event in past quite lot , have no idea how implement kind of behavior pthreads.

your appreciated
