I\'ve been working with large sparse files on openSUSE 11.2 x86_64. When I try to mmap() a 1TB sparse file, it fails with ENOMEM. I would have thought that the 64 bit address space would be adequate t
I\'m working some code including communication between processes, using semaphores. I made structure like this:
When using mmap() for shared memory (from Linux, or other UNIX-like systems) is it possible (and portable) to use fcntl() (or flock() or lockf() functions) to co-ordinate access to the mapping?
I am developing a active messaging protocol for parallel computation that replaces TCP/IP. My goal is to decrease the latency of a packet. Since the environment is a LAN, i c开发者_JS百科an replace TC

I\'m writing a high-loaded daemon that should be run on the FreeBSD 8.0 and on Linux as well. The main purpose of daemon is to pass files that are requested by their identifier. Identifier is converte
When using shared memory, each process may mmap the shared region into a different a开发者_如何学Gorea of its respective address space. This means that when storing pointers within the shared region,
If i have memory mapped a file of size 10GB in a 1GB machine and if i trigger a file i/o, after makin开发者_运维技巧g sure that the data requested is not in physical memory, will the fetched data get
