Subject Re: [PATCH] allow an APR app to choose underlying lock mechanism
Date Mon, 25 Jun 2001 21:21:05 GMT
I think this looks great.

Do I have any support yet for a fully-separated locks API, something
to the effect of:

Inter/cross process locks handled by:

Intraprocess locks handled by (these could even be POSIX):

(replace "*" above with each of {create, acquire, release, destroy, etc...})

I am expecting this kind of an API to work well with your changes below
(choosing the underlying lock mechanism).
