I reviewed the patch and did some editing.  I'll check
it in when I get the approval.

Comment 5

[Wan-Teh Chang]

I took a closer look at your patch and found that
its use of dup2() seems incorrect.  Also, the code
to set the current working directory for the new
process is incorrect.  I will attach a new patch,
which is my attempt to fix it although I didn't
implement the current working directory feature.

Is there online documentation for spawn()?

Can a threaded process call vfork()?

Comment 6

[Wan-Teh Chang]

Attachment: Proposed patch v2. Calls dup() instead of dup2() and does not implement the setting of working directory.

Comment 7

[Brian Edmond]

This patch works fine for me.

I checked in proposed patch v2 (attachment 37328 [details] [diff] [review]) on
the tip of NSPR.  Will check it in on the
NSPRPUB_PRE_4_2_CLIENT_BRANCH when the Mozilla tree
opens.
