We are trying to map the disk file and content is written in to specific offset. In meanwhile, if try to access the mmap'd content at specified offset, we are getting NULL value. we have not called msync() yet. the mmap called with MAP_SHARED. Is it possible that mmap content can differ on read after write or is this the problem happening because read is called before the msync().
Thanks, Prem
