## vfork()

Hi,
I was trying to get a multithreaded server to run on a uCLinux machine. However, the fork() was not supported with UCLinux and suggests the use of vfork().

My questions are:
1) Can we use exec() commands with vfork()? What are exec commands exactly?

2) Is it really possible to build a multithreaded server with vfork? Since it suspends the parents, I don't think that's possible. In fact, since the parent is suspended, we can surely rule out the possibility of concurrency. So what's the purpose of having vfork() in this case?

Regards,
JJ
