I am a green hand to multithreads. And now a problem strikes me
greatly,
would you give me a hand? On linux system, I want to write a program
which will
create several threads and fork a child process. And I hope parent
process and
the several threads would suspend for a time to wait for the child
process to
execute firstly. But now, I can only stop the father process while
threads are
reluctant to stop. I also set the thread atrribute inheritsched to be
PTHREAD_INHERIT_SCHED, hoping that when the process(also the father
thread) which
creates these threads blocks, these threads will suspend too. However,
my effort
seems to be useless. Would you give me some suggestions on how to stop
the threads
when waiting for the child process to execute?
