Does anyone know if mmap is thread safe? I didn't catch any thread
references in the man page.
I'm using mmap on a local file which is read into memory for searching
- no updates
Thanks

Yes, it is safe. Do be aware that it is up to the application to arbitrate
access to the mapped pages.

Each mapped file is accessed at most by a single thread so I should
not have any issues
