The Mmap module lets you use mmap to map in a file as a Perl variable
|
|
rather than reading the file into dynamically allocated memory.
|
|
|
|
The advantage of this is that several processes may share one copy of
|
|
the file or string, saving memory, and concurrently making changes to
|
|
portions of the file or string. When not used with a file, it is an
|
|
alternative to SysV shared memory that places no arbitrary size limits
|
|
on the shared memory area, and efficiently handles sparse memory usage.
