Windows pthread_create

This works very well but I got a redefinition error stackoverflow. It is -lpthread , not -pthread. How did you know that? The compiler and linker documentation lists the available options. Celeritas: 'cause I've done it before.

I agree that this is not particularly well documented - it is easy to find only if you already know! I will add some explanation. Would love some documentation for Windows. This seems to be using directories in Linux or Mac e. Add -lpthread to the linker command line. This fixed some problems which is good. How come I need to add this option to the linker and I've never had to supply the linker with options before? Celeritas Many functions, e. In the general case you need to explicitly tell the linker which libraries you need to link in though, and pthreads lives in its own library.

You mention, "Add -lpthread to the linker command line". How does one do this? How does one Add -lpthread to the linker command line?

I don't know the difference between -lpthread and -lpthreadGC2, but for some reason Mario's solution using -lpthreadGC2 works and -lpthread does not. Here's what happens currently as of now when using MinGW Installation Manager the mingw32 package manager for windows under Windows with the following packages installed: mingwlibpthreadgc-dll mingwlibpthreadgce-dll ERROR: gcc 5.

Also see the FAQs page of the link you shared. By installing gcc in MSYS2, you have automatically set up pthreads as well. You may want to see an example which proves that pthreads is working.

In short - the exact same code as on Linux works fine if you compile and run inside an MSYS2 terminal. Not necessarily always true, but true for the example in the link.

Main function is also a thread. Now suppose we have a function that we want to run in parallel to main function i.

If thread is created successfully then it will return 0. Where as, if thread creation is failed it will return error code to specify the error. We can use strerror to get the detail of error. But when main function ends, complete process exits and all the other thread will also be terminated.

The initial size of the stack, in bytes. The system rounds this value to the nearest page. If this parameter is 0 zero , the new thread uses the default size for the executable.

For more information, see Thread Stack Size. The function must exist in the remote process. For more information, see ThreadProc. If the function fails, the return value is NULL.

To get extended error information, call GetLastError. Note that CreateRemoteThread may succeed even if lpStartAddress points to data, code, or is not accessible.

If the start address is invalid when the thread runs, an exception occurs, and the thread terminates. Thread termination due to a invalid start address is handled as an error exit for the thread's process.
