我正在Linux上编写多线程程序,并希望在线程中创建一个进程,而不会结束其他线程。我查看了fork / exec,但在linux上的第3p节的exec手册页中说明了:
A call to any exec function from a process with more than one thread
shall result in all threads being terminated and the new executable
image being loaded and executed. No destructor functions shall be
called.
有没有办法在不终止其他线程的情况下生成新进程?
答案 0 :(得分:3)
但是如果你首先fork()和exec在子进程中,子进程只有一个线程,并且被exec函数销毁。父进程及其所有线程不受影响。
