Parent Thread Of Child Thread Suppose a process creates some threads say threadC and threadD. Later on each of these threads create new child threads say threadC1, threadC2, threadC3 etc. So a tree of threads will get created. Is there any way to find out the parent thread of one such...

How to handle one value below the other

Hi, I, have an output with 3 different values each below the other like: # echo $bla 123 345 234 Each value is in one line and for the further processing I need every single value. For example is there a way to grep line 2, like: # echo $bla | grep --line 2 345 :) Thank you in...

pthread_resume_np

PTHREAD_SUSPEND_NP(3)					   BSD Library Functions Manual 				     PTHREAD_SUSPEND_NP(3)

NAME

     pthread_suspend_np, pthread_resume_np -- suspend/resume the given thread

LIBRARY

     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS

     #include <pthread.h>

     int
     pthread_suspend_np(pthread_t thread);

     int
     pthread_resume_np(pthread_t thread);

DESCRIPTION

     The pthread_suspend_np() function suspends the thread given as argument.  If thread is the currently running thread as returned by
     pthread_self(3), the function fails and returns EDEADLK.  Otherwise, it removes the named thread from the running queue, and adds it to the
     suspended queue.  The thread will remain blocked until pthread_resume_np() is called on it.  In other words, pthread_resume_np() resumes the
     thread given as argument, if it was suspended.

RETURN VALUES

     Both functions return 0 on success and an error number indicating the reason for the failure.

COMPATIBILITY

     These functions are non-standard extensions.

ERRORS

     The pthread_suspend_np() function may fail if:

     [EDEADLK]		The thread requested to suspend was the currently running thread.

     [ESRCH]		The supplied thread was invalid.

     The pthread_resume_np() function may fail if:

     [ESRCH]		The supplied thread was invalid.

NOTES

     Some pthread_suspend_np() implementations may allow suspending the current thread.  This is dangerous, because the semantics of the function
     would then require the scheduler to schedule another thread, causing a thread context switch.  Since that context switch can happen in a sig-
     nal handler by someone calling pthread_suspend_np() in a signal handler, this is currently not allowed.

     In pthread_resume_np() the NetBSD implementation does not check if the thread argument is not already suspended.  Some implementations might
     return an error condition if pthread_resume_np() is called on a non-suspended thread.
