Re: [sqlite] Queries on SQLite
SQLite does not create the thread. The application creates the thread and then runs the async writer on that application created thread. --- () ascii ribbon campaign against html e-mail /\ www.asciiribbon.org > -Original Message- > From: sqlite-users-boun...@sqlite.org [mailto:sqlite-users- > boun...@sqlite.org] On Behalf Of Christian Smith > Sent: Friday, 15 June, 2012 04:01 > To: General Discussion of SQLite Database > Subject: Re: [sqlite] Queries on SQLite > > On Thu, Jun 14, 2012 at 06:27:17AM -0400, Richard Hipp wrote: > > On Thu, Jun 14, 2012 at 2:41 AM, vallur raghava reddy < > > vallur.raghavare...@gmail.com> wrote: > > > > > > > 2.

No it doesn't. You have to create the thread for the background I/O and then call sqlite3_async_run() in it. See the compilation and usage section of the documentation page you linked to.

It uses only POSIX interfaces on those systems. What does it mean for an ANSI-C code library to be "POSIX compliant"? SQLite also runs on Windows, OS/2, SymbianOS, QNX, and a host of other non-POSIX systems. Does that make it non-POSIX compliant? > 2. Does SQLite create a any threads?
