Full Discussion: Deliver values to Thread function
Top Forums Shell Programming and Scripting Deliver values to Thread function Post 302804255 by techmonk on Wednesday 8th of May 2013 10:03:57 AM

As per your code, main thread send only one int value to the "funktion1" thread.
After sending one int value, the main thread is modifying its value ten times.

If you want to send all 10 int values at a time, modify the struct as follows
Code:
struct Zahlen{int z1[10]; float z2[10];};

Then fill the structure in loop.

Pass the address of the structure variable to the "funktion1" thread.
Code:
res1 = pthread_create(&ptr1, NULL, (void *)&funktion1,(void *)&Zahl);

pthread_detach

PTHREAD_DETACH(3)					     Linux Programmer's Manual						 PTHREAD_DETACH(3)

NAME

       pthread_detach - detach a thread

SYNOPSIS

       #include <pthread.h>

       int pthread_detach(pthread_t thread);

       Compile and link with -pthread.

DESCRIPTION

       The  pthread_detach()  function	marks  the  thread identified by thread as detached.  When a detached thread terminates, its resources are
       automatically released back to the system without the need for another thread to join with the terminated thread.

       Attempting to detach an already detached thread results in unspecified behavior.

RETURN VALUE

       On success, pthread_detach() returns 0; on error, it returns an error number.

ERRORS

       EINVAL thread is not a joinable thread.

       ESRCH  No thread with the ID thread could be found.

ATTRIBUTES

       For an explanation of the terms used in this section, see attributes(7).

       +-----------------+---------------+---------+
       |Interface	 | Attribute	 | Value   |
       +-----------------+---------------+---------+
       |pthread_detach() | Thread safety | MT-Safe |
       +-----------------+---------------+---------+

CONFORMING TO

       POSIX.1-2001, POSIX.1-2008.

NOTES

       Once a thread has been detached, it can't be joined with pthread_join(3) or be made joinable again.

       A new thread can be created in a detached state using pthread_attr_setdetachstate(3) to set the detached attribute of the attr argument	of
       pthread_create(3).

       The  detached  attribute merely determines the behavior of the system when the thread terminates; it does not prevent the thread from being
       terminated if the process terminates using exit(3) (or equivalently, if the main thread returns).

       Either pthread_join(3) or pthread_detach() should be called for each thread that an application creates, so that system resources  for  the
       thread  can  be	released.  (But note that the resources of any threads for which one of these actions has not been done will be freed when
       the process terminates.)

EXAMPLE

       The following statement detaches the calling thread:

	   pthread_detach(pthread_self());
