c++ - 如何验证 pthread 函数是否开始执行

Question

例子:

void start(void){   pthread_create(&threadID, Null, run_thread_function,arguments);   //is there a way to ensure if the run_thread_function(basically new thread) started      //execution before returning from this(start) function    }

Answer 1

检查返回码。

if ((retcode = pthread_create(&threadID, Null, run_thread_function,arguments)) != 0)
{
   //something went wrong
}
