In the main function after the threads are created, the pthread_join() functions are called to wait for the two threads to complete. Once both the threads are complete, their return value is accessed by the second argument in the pthread_join() call. The output of the above code comes o...
In this example, we will explain howpthread_create()works. To do this, we will create a main function and from there open a thread that executes thethread_function()function in parallel with themain() function. The code for this example consists of two sections, themain()function and the...
In the following example, we demonstrate the program that creates 8 threads and executes the printHello function in each of them. Then, the calling thread waits for every thread with the pthread_join call in the loop. Notice that we also store the exit status code of threads in the retval...
I removed this flag from thereading_logs_with_offsetin commit293cd21after replacing usage ofpthreadswith C++'sstd::thread. Additionally, I didn't add that flag either to themultithreadexample added in commit4bf9616for the same reason. However, I'm getting the following error when building bo...

To compare and contrast multitasking between cooperating processes and multitasking using threads, let’s first look at how the simple C program inExample 1-1can be represented as a process (Figure 1-1), a process with a single thread (Figure 1-2), and, finally, as a process with multipl...

For example, if you are compiling your C program with the command: $ gcc -o threads posix_threads.c You will get the “undefined reference to pthreads” error. While making sure that the pthreads.h file is included in your header file; you need to compile your code with the right com...
