不 ，根据定义，线程共享一个地址空间。如果您需要单独的地址空间，您应该使用多个进程。

尽管不可能在具有不同虚拟地址空间的同一进程中拥有线程，但仍然可以拥有Thread Local Storage。你可能对此感兴趣。

It is not possible. Linux uses the clone system call to implement threads. The flags it takes include CLONE_THREAD, meaning the new process is placed in the same thread group as the calling process, and CLONE_VM, meaning the two processes/threads share virtual memory. Since Linux kernel version 2.6.0-test6, you cannot specify CLONE_THREAD without specifying CLONE_VM. (See the errors section of that link.)
However, depending on your exact motivation, you may be able to find a combination of flags for clone that do what you want.
